The HTML Handbook – Learn HTML for Beginners

Flavio Copes

Introduction

Welcome! I wrote this book to help you quickly learn HTML and get familiar with the advanced HTML topics.

HTML, a shorthand for Hyper Text Markup Language, is one of the most fundamental building blocks of the Web.

HTML was officially born in 1993 and since then it evolved into its current state, moving from simple text documents to powering rich Web Applications.

This handbook is aimed at a vast audience.

First, the beginner. I explain HTML from zero in a succinct but comprehensive way, so you can use this book to learn HTML from the basics.

Then, the professional. HTML is often considered like a secondary thing to learn. It might be given for granted.

Yet lots of things are obscure to many people. Me included. I wrote this handbook to help my understanding of the topic, because when I need to explain something, I better make sure I first know the thing inside out.

Even if you don't write HTML in your day to day work, knowing how HTML works can help save you some headaches when you need to understand it from time to time, for example while tweaking a web page.

HTML is the foundation of the marvel called the Web.

There is an incredible power underneath this rather simple and limited set of rules, which lets us -- developers, makers, designers, writers, and tinkerers -- craft documents, apps, and experiences for people all around the globe.

My first HTML book came out in 1997 and was called "HTML Unleashed". A big, lots-of-pages, long tome.

20+ years have passed, and HTML is still the foundation of the Web, with minimal changes from back then.

Sure, we got more semantic tags, presentational HTML is no longer a thing, and CSS has taken care of the design of things.

HTML's success is based on one thing: simplicity .

It resisted being hijacked into an XML dialect via XHTML, when eventually people realized that thing was way, way too complex.

It did so because of another feature it provides us: forgiveness . There are some rules, right, but after you learn those, you have a lot of freedom.

Browsers learned to be resilient and to always try to do their best when parsing and presenting HTML to the users.

And the whole Web platform did one thing right: it never broke backward compatibility. Pretty incredibly, we can go back to HTML documents written in 1991, and they look pretty much as they looked back then.

We even know what the first web page was. It's this: http://info.cern.ch/hypertext/WWW/TheProject.html

And you can see the source of the page, thanks to another big feature of the Web and HTML: we can inspect the HTML of any web page .

Don't take this for granted. I don't know any other platform that gives us this ability.

The exceptional Developer Tools built into any browser let us inspect and take inspiration from HTML written by anyone in the world.

If you are new to HTML this book aims to help you get started. If you are a seasoned Web Developer this book will improve your knowledge.

I learned so much while writing it, even though I've been working with the Web for 20+ years, and I'm sure you'll find something new, too.

Or you'll re-learn something old you forgot.

In any case, the goal of the book is to be useful to you, and I hope it succeeds.

HTML BASICS

HTML is a standard defined by the WHATWG , an acronym for Web Hypertext Application Technology Working Group, an organization formed by people working on the most popular web browser. This means it's basically controlled by Google, Mozilla, Apple and Microsoft.

In the past the W3C (World Wide Web Consortium) was the organization in charge of creating the HTML standard.

The control informally moved from W3C to WHATWG when it became clear that the W3C push towards XHTML was not a good idea.

If you've never heard of XHTML, here's a short story. In the early 2000s, we all believed the future of the Web was XML (seriously). So HTML moved from being an SGML-based authoring language to an XML markup language.

It was a big change. We had to know, and respect, more rules. Stricter rules.

Eventually browser vendors realized this was not the right path for the Web, and they pushed back, creating what is now known as HTML5.

W3C did not really agree on giving up control of HTML, and for years we had 2 competing standards, each one aiming to be the official one. Eventually on 28 May 2019 it was made official by W3C that the "true" HTML version was the one published by WHATWG.

I mentioned HTML5. Let me explain this little story. I know, it's kind of confusing up to now, as with many things in life when many actors are involved, yet it's also fascinating.

We had HTML version 1 in 1993. Here's the original RFC .

HTML 2 followed in 1995.

We got HTML 3 in January 1997, and HTML 4 in December 1997.

Busy times!

20+ years went by, we had this entire XHTML thing, and eventually we got to this HTML5 "thing", which is not really just HTML any more.

HTML5 is a term that now defines a whole set of technologies, which includes HTML but adds a lot of APIs and standards like WebGL, SVG and more.

The key thing to understand here is this: there is no such thing (any more) as an HTML version now. It's a living standard. Like CSS, which is called "3", but in reality is a bunch of independent modules developed separately. Like JavaScript, where we have one new edition each year, but nowadays, the only thing that matters is which individual features are implemented by the engine.

Yes we call it HTML5, but HTML4 is from 1997. That's a long time for anything, let alone for the web.

This is where the standard now "lives": https://html.spec.whatwg.org/multipage .

HTML is the markup language we use to structure content that we consume on the Web.

HTML is served to the browser in different ways.

  • It can be generated by a server-side application that builds it depending on the request or the session data, for example a Rails or Laravel or Django application.
  • It can be generated by a JavaScript client-side application that generates HTML on the fly.
  • In the simplest case, it can be stored in a file and served to the browser by a Web server.

Let's dive into this last case. Although in practice it's probably the least popular way to generate HTML, it's still essential to know the basic building blocks.

By convention, an HTML file is saved with a .html or .htm extension.

Inside this file, we organize the content using tags .

Tags wrap the content, and each tag gives a special meaning to the text it wraps.

Let's make a few examples.

This HTML snippet creates a paragraph using the p tag:

This HTML snippet creates a list of items using the ul tag, which means unordered list , and the li tags, which mean list item :

When an HTML page is served by the browser, the tags are interpreted, and the browser renders the elements according to the rules that define their visual appearance.

Some of those rules are built-in, such as how a list renders or how a link is underlined in blue.

Some other rules are set by you with CSS.

HTML is not presentational. It's not concerned with how things look . Instead, it's concerned with what things mean .

It's up to the browser to determine how things look, with the directives defined by who builds the page, with the CSS language.

Now, those two examples I made are HTML snippets taken outside of a page context.

HTML page structure

Let's make an example of a proper HTML page.

Things start with the Document Type Declaration (aka doctype ), a way to tell the browser this is an HTML page, and which version of HTML we are using.

Modern HTML uses this doctype:

Then we have the html element, which has an opening and closing tag:

Most tags come in pairs with an opening tag and a closing tag. The closing tag is written the same as the opening tag, but with a / :

There are a few self-closing tags, which means they don't need a separate closing tag as they don't contain anything in them .

The html starting tag is used at the beginning of the document, right after the document type declaration.

The html ending tag is the last thing present in an HTML document.

Inside the html element we have 2 elements: head and body :

Inside head we will have tags that are essential to creating a web page, like the title, the metadata, and internal or external CSS and JavaScript. Mostly things that do not directly appear on the page, but only help the browser (or bots like the Google search bot) display it properly.

Inside body we will have the content of the page. The visible stuff .

Tags vs elements

I mentioned tags and elements. What's the difference?

Elements have a starting tag and a closing tag. In this example, we use the p starting and closing tags to create a p element:

So, an element constitutes the whole package :

  • starting tag
  • text content (and possibly other elements)
  • closing tag

If an element has doesn't have a closing tag, it is only written with the starting tag, and it cannot contain any text content.

That said, I might use the tag or element term in the book meaning the same thing, except if I explicitly mention starting tag or ending tag.

The starting tag of an element can have special snippets of information we can attach, called attributes .

Attributes have the key="value" syntax:

You can also use single quotes, but using double quotes in HTML is a nice convention.

We can have many of them:

and some attributes are boolean, meaning you only need the key:

The class and id attributes are two of the most common you will find used.

They have a special meaning, and they are useful both in CSS and JavaScript.

The difference between the two is that an id is unique in the context of a web page; it cannot be duplicated.

Classes, on the other hand, can appear multiple times on multiple elements.

Plus, an id is just one value. class can hold multiple values, separated by a space:

It's common to use the dash - to separate words in a class value, but it's just a convention.

Those are just two of the possible attributes you can have. Some attributes are only used for one tag. They are highly specialized.

Other attributes can be used in a more general way. You just saw id and class , but we have other ones too, like style which can be used to insert inline CSS rules on an element.

Case insensitive

HTML is case insensitive. Tags can be written in all caps, or lowercase. In the early days, caps were the norm. Today lowercase is the norm. It is a convention.

You usually write like this:

not like this:

White space

Pretty important. In HTML, even if you add multiple white spaces into a line, it's collapsed by the browser's CSS engine.

For example the rendering of this paragraph:

is the same as this:

and the same as this:

> Using the white-space CSS property you can change how things behave. You can find more information on how CSS processes white space in the CSS Spec

I typically favor

Nested tags should be indented with 2 or 4 characters, depending on your preference:

Note: this "white space is not relevant" feature means that if you want to add additional space, it can make you pretty mad. I suggest you use CSS to make more space when needed.

Note: in special cases, you can use the   HTML entity (an acronym that means non-breaking space ) - more on HTML entities later on. I think this should not be abused. CSS is always preferred to alter the visual presentation.

THE DOCUMENT HEADING

The head tag contains special tags that define the document properties.

It's always written before the body tag, right after the opening html tag:

We never use attributes on this tag. And we don't write content in it.

It's just a container for other tags. Inside it we can have a wide variety of tags, depending on what you need to do:

The title tag

The title tag determines the page title. The title is displayed in the browser, and it's especially important as it's one of the key factors for Search Engine Optimization (SEO).

The script tag

This tag is used to add JavaScript into the page.

You can include it inline, using an opening tag, the JavaScript code and then the closing tag:

Or you can load an external JavaScript file by using the src attribute:

The type attribute by default is set to text/javascript , so it's completely optional.

There is something pretty important to know about this tag.

Sometimes this tag is used at the bottom of the page, just before the closing </body> tag. Why? For performance reasons.

Loading scripts by default blocks the rendering of the page until the script is parsed and loaded.

By putting it at the bottom of the page, the script is loaded and executed after the whole page is already parsed and loaded, giving a better experience to the user over keeping it in the head tag.

My opinion is that this is now bad practice. Let script live in the head tag.

In modern JavaScript we have an alternative this is more performant than keeping the script at the bottom of the page -- the defer attribute. This is an example that loads a file.js file, relative to the current URL:

This is the scenario that triggers the faster path to a fast-loading page, and fast-loading JavaScript.

Note: the async attribute is similar, but in my opinion a worse option than defer . I describe why, in more detail, on page https://flaviocopes.com/javascript-async-defer/

The noscript tag

This tag is used to detect when scripts are disabled in the browser.

Note: users can choose to disable JavaScript scripts in the browser settings. Or the browser might not support them by default.

It is used differently depending on whether it's put in the document head or in the document body.

We're talking about the document head now, so let's first introduce this usage.

In this case, the noscript tag can only contain other tags:

to alter the resources served by the page, or the meta information, if scripts are disabled.

In this example I set an element with the no-script-alert class to display if scripts are disabled, as it was display: none by default:

Let's solve the other case: if put in the body, it can contain content, like paragraphs and other tags, which are rendered in the UI.

The link tag

The link tag is used to set relationships between a document and other resources.

It's mainly used to link an external CSS file to be loaded.

This element has no closing tag.

The media attribute allows the loading of different stylesheets depending on the device capabilities:

We can also link to resources other than stylesheets.

For example we can associate an RSS feed using

Or we can associate a favicon using:

This tag was also used for multi-page content, to indicate the previous and next page using rel="prev" and rel="next" . Mostly for Google. As of 2019, Google announced it does not use this tag any more because it can find the correct page structure without it.

The style tag

This tag can be used to add styles into the document, rather than loading an external stylesheet.

As with the link tag, you can use the media attribute to use that CSS only on the specified medium:

The base tag

This tag is used to set a base URL for all relative URLs contained in the page.

The meta tag

Meta tags perform a variety of tasks and they are very, very important.

Especially for SEO.

meta elements only have the starting tag.

The most basic one is the description meta tag:

This might be used by Google to generate the page description in its result pages, if it finds it better describes the page than the on-page content (don't ask me how).

The charset meta tag is used to set the page character encoding. utf-8 in most cases:

The robots meta tag instructs the Search Engine bots whether to index a page or not:

Or if they should follow links or not:

You can set nofollow on individual links, too. This is how you can set nofollow globally.

You can combine them:

The default behavior is index, follow .

You can use other properties, including nosnippet , noarchive , noimageindex and more.

You can also just tell Google instead of targeting all search engines:

And other search engines might have their own meta tag, too.

Speaking of which, we can tell Google to disable some features. This prevents the translate functionality in the search engine results:

The viewport meta tag is used to tell the browser to set the page width based on the device width.

See more about this tag .

Another rather popular meta tag is the http-equiv="refresh" one. This line tells the browser to wait 3 seconds, then redirect to that other page:

Using 0 instead of 3 will redirect as soon as possible.

This is not a full reference; Other less-used meta tags exist.

After this document heading introduction, we can start diving into the document body.

THE DOCUMENT BODY

After the closing head tag, we can only have one thing in an HTML document: the body element.

Just like the head and html tags, we can only have one body tag in one page.

Inside the body tag we have all the tags that define the content of the page.

Technically, the start and ending tags are optional. But I consider it a good practice to add them. Just for clarity.

In the next chapters we'll define the variety of tags you can use inside the page body.

But before, we must introduce a difference between block elements and inline elements.

Block elements vs inline elements

Visual elements, the ones defined in the page body, can be generally classified in 2 categories:

  • block elements ( p , div , heading elements, lists and list items, ...)
  • inline elements ( a , span , img , ...)

What is the difference?

Block elements, when positioned in the page, do not allow other elements next to them. To the left, or to the right.

Inline elements instead can sit next to other inline elements.

The difference also lies in the visual properties we can edit using CSS. We can alter the width/height, margin, padding and border of block elements. We can't do that for inline elements.

Note that using CSS we can change the default for each element, setting a p tag to be inline, for example, or a span to be a block element.

Another difference is that inline elements can be contained in block elements. The reverse is not true.

Some block elements can contain other block elements, but it depends. The p tag for example does not allow such option.

TAGS THAT INTERACT WITH TEXT

This tag defines a paragraph of text.

It's a block element.

Inside it, we can add any inline element we like, like span or a .

We cannot add block elements.

We cannot nest a p element into another one.

By default browsers style a paragraph with a margin on top and at the bottom. 16px in Chrome, but the exact value might vary between browsers.

This causes two consecutive paragraphs to be spaced, replicating what we think of a "paragraph" in printed text.

The span tag

This is an inline tag that can be used to create a section in a paragraph that can be targeted using CSS:

This tag represents a line break. It's an inline element, and does not need a closing tag.

We use it to create a new line inside a p tag, without creating a new paragraph.

And compared to creating a new paragraph, it does not add additional spacing.

The heading tags

HTML provides us 6 heading tags. From most important to least important, we have h1 , h2 , h3 , h4 , h5 , h6 .

Typically a page will have one h1 element, which is the page title. Then you might have one or more h2 elements depending on the page content.

Headings, especially the heading organization, are also essential for SEO, and search engines use them in various ways.

The browser by default will render the h1 tag bigger, and will make the elements size smaller as the number near h increases:

Screen-Shot-2019-06-11-at-19.46.57

All headings are block elements. They cannot contain other elements, just text.

The strong tag

This tag is used to mark the text inside it as strong . This is pretty important, it's not a visual hint, but a semantic hint. Depending on the medium used, its interpretation will vary.

Browsers by default make the text in this tag bold .

This tag is used to mark the text inside it as emphasized . Like with strong , it's not a visual hint but a semantic hint.

Browsers by default make the text in this italic .

The blockquote HTML tag is useful to insert citations in the text.

Browsers by default apply a margin to the blockquote element. Chrome applies a 40px left and right margin, and a 10px top and bottom margin.

The q HTML tag is used for inline quotes.

Horizontal line

Not really based on text, but the hr tag is often used inside a page. It means horizontal rule , and it adds a horizontal line in the page.

Useful to separate sections in the page.

Code blocks

The code tag is especially useful to show code, because browsers give it a monospaced font.

That's typically the only thing that browsers do. This is the CSS applied by Chrome:

This tag is typically wrapped in a pre tag, because the code element ignores whitespace and line breaks. Like the p tag.

Chrome gives pre this default styling:

which prevents white space collapsing and makes it a block element.

We have 3 types of lists:

  • unordered lists
  • ordered lists
  • definition lists

Unordered lists are created using the ul tag. Each item in the list is created with the li tag:

Ordered lists are similar, just made with the ol tag:

The difference between the two is that ordered lists have a number before each item:

Screen-Shot-2019-06-12-at-09.35.05

Definition lists are a bit different. You have a term, and its definition:

This is how browsers typically render them:

Screen-Shot-2019-06-12-at-09.45.21

I must say you rarely see them in the wild, for sure not much as ul and ol , but sometimes they might be useful.

Other text tags

There is a number of tags with presentational purposes:

  • the mark tag
  • the ins tag
  • the del tag
  • the sup tag
  • the sub tag
  • the small tag

This is an example of the visual rendering of them which is applied by default by browsers:

Screen-Shot-2019-06-12-at-08.43.55

You might wonder, how is b different than strong ? And how i is different than em ?

The difference lies in the semantic meaning. While b and i are a direct hint at the browser to make a piece of text bold or italic, strong and em give the text a special meaning, and it's up to the browser to give the styling. Which happens to be exactly the same as b and i , by default. Although you can change that using CSS.

There are a number of other, less used tags related to text. I just mentioned the ones that I see used the most.

Links are defined using the a tag. The link destination is set via its href attribute.

Between the starting and closing tag we have the link text.

The above example is an absolute URL. Links also work with relative URLs:

In this case, when clicking the link the user is moved to the /test URL on the current origin.

Be careful with the / character. If omitted, instead of starting from the origin, the browser will just add the test string to the current URL.

Example, I'm on the page https://flaviocopes.com/axios/ and I have these links:

  • /test once clicked brings me to https://flaviocopes.com/test
  • test once clicked brings me to https://flaviocopes.com/axios/test

Link tags can include other things inside them, not just text. For example, images:

or any other elements, except other <a> tags.

If you want to open the link in a new tab, you can use the target attribute:

CONTAINER TAGS AND PAGE STRUCTURE HTML

Container tags.

HTML provides a set of container tags. Those tags can contain an unspecified set of other tags.

and it can be confusing to understand the difference between them.

Let's see when to use each one of them.

The article tag identifies a thing that can be independent from other things in a page.

For example a list of blog posts in the homepage.

Or a list of links.

We're not limited to lists: an article can be the main element in a page.

Inside an article tag we should have a title ( h1 - h6 ) and

Represents a section of a document. Each section has a heading tag ( h1 - h6 ), then the section body .

It's useful to break a long article into different sections .

Shouldn't be used as a generic container element. div is made for this.

div is the generic container element:

You often add a class or id attribute to this element, to allow it to be styled using CSS.

We use div in any place where we need a container but the existing tags are not suited.

Tags related to page

This tag is used to create the markup that defines the page navigation. Into this we typically add an ul or ol list:

The aside tag is used to add a piece of content that is related to the main content.

A box where to add a quote, for example. Or a sidebar.

Using aside is a signal that the things it contains are not part of the regular flow of the section it lives into.

The header tag represents a part of the page that is the introduction. It can for example contain one or more heading tag ( h1 - h6 ), the tagline for the article, an image.

The main tag represents the main part of a page:

The footer tag is used to determine the footer of an article, or the footer of the page:

Forms are the way you can interact with a page, or an app, built with Web technologies.

You have a set of controls, and when you submit the form, either with a click to a "submit" button or programmatically, the browser will send the data to the server.

By default this data sending causes the page to reload after the data is sent, but using JavaScript you can alter this behavior (not going to explain how in this book).

A form is created using the form tag:

By default forms are submitted using the GET HTTP method. Which has its drawbacks, and usually you want to use POST.

You can set the form to use POST when submitted by using the method attribute:

The form is submitted, either using GET or POST, to the same URL where it resides.

So if the form is in the https://flaviocopes.com/contacts page, pressing the "submit" button will make a request to that same URL.

Which might result in nothing happening.

You need something server-side to handle the request, and typically you "listen" for those form submit events on a dedicated URL.

You can specify the URL via the action parameter:

This will cause the browser to submit the form data using POST to the /new-contact URL on the same origin.

If the origin (protocol + domain + port) is https://flaviocopes.com (port 80 is the default), this means the form data will be sent to https://flaviocopes.com/new-contact .

I talked about data. Which data?

Data is provided by users via the set of controls that are available on the Web platform:

  • input boxes (single line text)
  • text areas (multiline text)
  • select boxes (choose one option from a drop-down menu)
  • radio buttons (choose one option from a list always visible)
  • checkboxes (choose zero, one or more option)
  • file uploads

Let's introduce each one of them in the following form fields overview.

The input tag

The input field is one of the most widely used form elements. It's also a very versatile element, and it can completely change behavior based on the type attribute.

The default behavior is to be a single-line text input control:

Equivalent to using:

As with all the other fields that follow, you need to give the field a name in order for its content to be sent to the server when the form is submitted:

The placeholder attribute is used to have some text showing up, in light gray, when the field is empty. Useful to add a hint to the user for what to type in:

Using type="email" will validate client-side (in the browser) an email for correctness (semantic correctness, not ensuring the email address is existing) before submitting.

Using type="password" will make every key entered appear as an asterisk (*) or dot, useful for fields that host a password.

You can have an input element accept only numbers:

You can specify a minimum and maximum value accepted:

The step attribute helps identify the steps between different values. For example this accepts a value between 10 and 50, at steps of 5:

Hidden field

Fields can be hidden from the user. They will still be sent to the server upon the form submit:

This is commonly used to store values like a CSRF token, used for security and user identification, or even to detect robots sending spam, using special techniques.

It can also just be used to identify a form and its action.

Setting a default value

All those fields accept a predefined value. If the user does not change it, this will be the value sent to the server:

If you set a placeholder, that value will appear if the user clears the input field value:

Form submit

The type="submit" field is a button that, once pressed by the user, submits the form:

The value attribute sets the text on the button, which if missing shows the "Submit" text:

Form validation

Browsers provide client-side validation functionality to forms.

You can set fields as required, ensuring they are filled, and enforce a specific format for the input of each field.

Let's see both options.

Set fields as required

The required attribute helps you with validation. If the field is not set, client-side validation fails and the browser does not submit the form:

Enforce a specific format

I described the type="email" field above. It automatically validates the email address according to a format set in the specification.

In the type="number" field, I mentioned the min and max attribute to limit values entered to an interval.

You can do more.

You can enforce a specific format on any field.

The pattern attribute gives you the ability to set a regular expression to validate the value against.

I recommend reading my Regular Expressions Guide at flaviocopes.com/javascript-regular-expressions/ .

pattern=" https://.* "

Other fields

File uploads.

You can load files from your local computer and send them to the server using a type="file" input element:

You can attach multiple files:

You can specify one or more file types allowed using the accept attribute. This accepts images:

You can use a specific MIME type, like application/json or set a file extension like .pdf . Or set multiple file extensions, like this:

The type="button" input fields can be used to add additional buttons to the form, that are not submit buttons:

They are used to programmatically do something, using JavaScript.

There is a special field rendered as a button, whose special action is to clear the entire form and bring back the state of the fields to the initial one:

Radio buttons

Radio buttons are used to create a set of choices, of which one is pressed and all the others are disabled.

The name comes from old car radios that had this kind of interface.

You define a set of type="radio" inputs, all with the same name attribute, and different value attribute:

Once the form is submitted, the color data property will have one single value.

There's always one element checked. The first item is the one checked by default.

You can set the value that's pre-selected using the checked attribute. You can use it only once per radio inputs group.

Similar to radio boxes, but they allow multiple values to be chosen, or none at all.

You define a set of type="checkbox" inputs, all with the same name attribute, and different value attribute:

All those checkboxes will be unchecked by default. Use the checked attribute to enable them on page load.

Since this input field allows multiple values, upon form submit the value(s) will be sent to the server as an array.

Date and time

We have a few input types to accept date values.

The type="date" input field allows the user to enter a date, and shows a date picker if needed:

The type="time" input field allows the user to enter a time, and shows a time picker if needed:

The type="month" input field allows the user to enter a month and a year:

The type="week" input field allows the user to enter a week and a year:

All those fields allow to limit the range and the step between each value. I recommend checking MDN for the little details on their usage.

The type="datetime-local" field lets you choose a date and a time.

Here is a page to test them all: https://codepen.io/flaviocopes/pen/ZdWQPm

Color picker

You can let users pick a color using the type="color" element:

You set a default value using the value attribute:

The browser will take care of showing a color picker to the user.

This input element shows a slider element. People can use it to move from a starting value to an ending value:

You can provide an optional step:

The type="tel" input field is used to enter a phone number:

The main selling point for using tel over text is on mobile, where the device can choose to show a numeric keyboard.

Specify a pattern attribute for additional validation:

The type="url" field is used to enter a URL.

You can validate it using the pattern attribute:

The textarea tag

The textarea element allows users to enter multi-line text. Compared to input , it requires an ending tag:

You can set the dimensions using CSS, but also using the rows and cols attributes:

As with the other form tags, the name attribute determines the name in the data sent to the server:

The select tag

This tag is used to create a drop-down menu.

The user can choose one of the options available.

Each option is created using the option tag. You add a name to the select, and a value to each option:

You can set an option disabled:

You can have one empty option:

Options can be grouped using the optgroup tag. Each option group has a label attribute:

In the early days of the web tables were a very important part of building layouts.

Later on they were replaced by CSS and its layout capabilities, and today we have powerful tools like CSS Flexbox and CSS Grid to build layouts. Tables are now used just for, guess what, building tables!

The table tag

You define a table using the table tag:

Inside the table we'll define the data. We reason in terms of rows, which means we add rows into a table (not columns). We'll define columns inside a row.

A row is added using the tr tag, and that's the only thing we can add into a table element:

This is a table with 3 rows.

The first row can take the role of the header.

Column headers

The table header contains the name of a column, typically in a bold font.

Think about an Excel / Google Sheets document. The top A-B-C-D... header.

Screen-Shot-2019-06-20-at-10.18.17

We define the header using the th tag:

The table content

The content of the table is defined using td tags, inside the other tr elements:

This is how browsers render it, if you don't add any CSS styling:

Screen-Shot-2019-06-20-at-10.24.08

Adding this CSS:

makes the table look more like a proper table:

Span columns and rows

A row can decide to span over 2 or more columns, using the colspan attribute:

Screen-Shot-2019-06-20-at-10.27.59

Or it can span over 2 or more rows, using the rowspan attribute:

Screen-Shot-2019-06-20-at-10.29.37

Row headings

Before I explained how you can have column headings, using the th tag inside the first tr tag of the table.

You can add a th tag as the first element inside a tr that's not the first tr of the table, to have row headings:

Screen-Shot-2019-06-20-at-10.49.16

More tags to organize the table

You can add 3 more tags into a table, to have it more organized.

This is best when using big tables. And to properly define a header and a footer, too.

Those tags are

They wrap the tr tags to clearly define the different sections of the table. Here's an example:

Screen-Shot-2019-06-20-at-10.52.41

Table caption

A table should have a caption tag that describes its content. That tag should be put immediately after the opening table tag:

MULTIMEDIA TAGS: AUDIO AND VIDEO

In this section I want to show you the audio and video tags.

The audio tag

This tag allows you to embed audio content in your HTML pages.

This element can stream audio, maybe using a microphone via getUserMedia() , or it can play an audio source which you reference using the src attribute:

By default the browser does not show any controls for this element. Which means the audio will play only if set to autoplay (more on this later) and the user can't see how to stop it or control the volume or move through the track.

To show the built-in controls, you can add the controls attribute:

Controls can have a custom skin.

You can specify the MIME type of the audio file using the type attribute. If not set, the browser will try to automatically determine it:

An audio file by default does not play automatically. Add the autoplay attribute to play the audio automatically:

Note: mobile browsers don't allow autoplay

The loop attribute restarts the audio playing at 0:00 if set; otherwise, if not present, the audio stops at the end of the file:

You can also play an audio file muted using the muted attribute (not really sure what's the usefulness of this):

Using JavaScript you can listen for various events happening on an audio element, the most basic of which are:

  • play when the file starts playing
  • pause when the audio playing was paused
  • playing when the audio is resumed from a pause
  • ended when the end of the audio file was reached

The video tag

This tag allows you to embed video content in your HTML pages.

This element can stream video, using a webcam via getUserMedia() or WebRTC , or it can play a video source which you reference using the src attribute:

By default the browser does not show any controls for this element, just the video.

Which means the video will play only if set to autoplay (more on this later) and the user can't see how to stop it, pause it, control the volume or skip to a specific position in the video.

You can specify the MIME type of the video file using the type attribute. If not set, the browser will try to automatically determine it:

A video file by default does not play automatically. Add the autoplay attribute to play the video automatically:

Some browsers also require the muted attribute to autoplay. The video autoplays only if muted:

The loop attribute restarts the video playing at 0:00 if set; otherwise, if not present, the video stops at the end of the file:

You can set an image to be the poster image:

If not present, the browser will display the first frame of the video as soon as it's available.

You can set the width and height attributes to set the space that the element will take so that the browser can account for it and it does not change the layout when it's finally loaded. It takes a numeric value, expressed in pixels.

Using JavaScript you can listen for various events happening on an video element, the most basic of which are:

  • pause when the video was paused
  • playing when the video is resumed from a pause
  • ended when the end of the video file was reached

The iframe tag allows us to embed content coming from other origins (other sites) into our web page.

Technically, an iframe creates a new nested browsing context. This means that anything in the iframe does not interfere with the parent page, and vice versa. JavaScript and CSS do not "leak" to/from iframes.

Many sites use iframes to perform various things. You might be familiar with Codepen, Glitch or other sites that allow you to code in one part of the page, and you see the result in a box. That's an iframe.

You create one this way:

You can load an absolute URL, too:

You can set a set of width and height parameters (or set them using CSS) otherwise the iframe will use the defaults, a 300x150 pixels box:

The srcdoc attribute lets you specify some inline HTML to show. It's an alternative to src , but recent and not supported in Edge 18 and lower, and in IE:

The sandbox attribute allows us to limit the operations allowed in the iframes.

If we omit it, everything is allowed:

If we set it to "", nothing is allowed:

We can select what to allow by adding options in the sandbox attribute. You can allow multiple ones by adding a space in between. Here's an incomplete list of the options you can use:

  • allow-forms : allow to submit forms
  • allow-modals allow to open modals windows, including calling alert() in JavaScript
  • allow-orientation-lock allow to lock the screen orientation
  • allow-popups allow popups, using window.open() and target="_blank" links
  • allow-same-origin treat the resource being loaded as same origin
  • allow-scripts lets the loaded iframe run scripts (but not create popups).
  • allow-top-navigation gives access to the iframe to the top level browsing context

Currently experimental and only supported by Chromium-based browsers, this is the future of resource sharing between the parent window and the iframe.

It's similar to the sandbox attribute, but lets us allow specific features, including:

  • accelerometer gives access to the Sensors API Accelerometer interface
  • ambient-light-sensor gives access to the Sensors API AmbientLightSensor interface
  • autoplay allows to autoplay video and audio files
  • camera allows to access the camera from the getUserMedia API
  • display-capture allows to access the screen content using the getDisplayMedia API
  • fullscreen allows to access fullscreen mode
  • geolocation allows to access the Geolocation API
  • gyroscope gives access to the Sensors API Gyroscope interface
  • magnetometer gives access to the Sensors API Magnetometer interface
  • microphone gives access to the device microphone using the getUserMedia API
  • midi allows access to the Web MIDI API
  • payment gives access to the Payment Request API
  • speaker allows access to playing audio through the device speakers
  • usb gives access to the WebUSB API.
  • vibrate gives access to the Vibration API
  • vr gives access to the WebVR API

When loading an iframe, the browser sends it important information about who is loading it in the Referer header (notice the single r , a typo we must live with).

The misspelling of referrer originated in the original proposal by computer scientist Phillip Hallam-Baker to incorporate the field into the HTTP specification. The misspelling was set in stone by the time of its incorporation into the Request for Comments standards document RFC 1945

The referrerpolicy attribute lets us set the referrer to send to the iframe when loading it. The referrer is an HTTP header that lets the page know who is loading it. These are the allowed values:

  • no-referrer-when-downgrade it's the default, and does not send the referrer when the current page is loaded over HTTPS and the iframe loads on the HTTP protocol
  • no-referrer does not send the referrer header
  • origin the referrer is sent, and only contains the origin (port, protocol, domain), not the origin + path which is the default
  • origin-when-cross-origin when loading from the same origin (port, protocol, domain) in the iframe, the referrer is sent in its complete form (origin + path). Otherwise only the origin is sent
  • same-origin the referrer is sent only when loading from the same origin (port, protocol, domain) in the iframe
  • strict-origin sends the origin as the referrer if the current page is loaded over HTTPS and the iframe also loads on the HTTPS protocol. Sends nothing if the iframe is loaded over HTTP
  • strict-origin-when-cross-origin sends the origin + path as the referrer when working on the same origin. Sends the origin as the referrer if the current page is loaded over HTTPS and the iframe also loads on the HTTPS protocol. Sends nothing if the iframe is loaded over HTTP
  • unsafe-url : sends the origin + path as the referrer even when loading resources from HTTP and the current page is loaded over HTTPS

Images can be displayed using the img tag.

This tag accepts a src attribute, which we use to set the image source:

We can use a wide set of images. The most common ones are PNG, JPEG, GIF, SVG and more recently WebP.

The HTML standard requires an alt attribute to be present, to describe the image. This is used by screen readers and also by search engine bots:

You can set the width and height attributes to set the space that the element will take, so that the browser can account for it and it does not change the layout when it's fully loaded. It takes a numeric value, expressed in pixels.

The figure tag

The figure tag is often used along with the img tag.

figure is a semantic tag often used when you want to display an image with a caption. You use it like this:

The figcaption tag wraps the caption text.

Responsive images using srcset

The srcset attribute allows you to set responsive images that the browser can use depending on the pixel density or window width, according to your preferences. This way, it can only download the resources it needs to render the page, without downloading a bigger image if it's on a mobile device, for example.

Here's an example, where we give 4 additional images for 4 different screen sizes:

In the srcset we use the w measure to indicate the window width.

Since we do so, we also need to use the sizes attribute:

In this example the (max-width: 500px) 100vw, (max-width: 900px) 50vw, 800px string in the sizes attribute describes the size of the image in relation to the viewport, with multiple conditions separated by a semicolon.

The media condition max-width: 500px sets the size of the image in correlation to the viewport width. In short, if the window size is < 500px, it renders the image at 100% of the window size.

If the window size is bigger but < 900px , it renders the image at 50% of the window size.

And if even bigger, it renders the image at 800px.

The vw unit of measure can be new to you, and in short we can say that 1 vw is 1% of the window width, so 100vw is 100% of the window width.

A useful website to generate the srcset and progressively smaller images is https://responsivebreakpoints.com/ .

The picture tag

HTML also gives us the picture tag, which does a very similar job to srcset , and the differences are very subtle.

You use picture when instead of just serving a smaller version of a file, you completely want to change it. Or serve a different image format.

The best use case I found is when serving a WebP image, which is a format still not widely supported. In the picture tag you specify a list of images, and they will be used in order, so in the next example, browsers that support WebP will use the first image, and fallback to JPG if not:

The source tag defines one (or more) formats for the images. The img tag is the fallback in case the browser is very old and does not support the picture tag.

In the source tag inside picture you can add a media attribute to set media queries.

The example that follows kind of works like the above example with srcset :

But that's not its use case, because as you can see it's much more verbose.

The picture tag is recent but is now supported by all the major browsers except Opera Mini and IE (all versions).

ACCESSIBILITY

It's important we design our HTML with accessibility in mind.

Having accessible HTML means that people with disabilities can use the Web. There are totally blind or visually impaired users, people with hearing loss issues and a multitude of other different disabilities.

Unfortunately this topic does not take the importance it needs, and it doesn't seem as cool as others.

What if a person can't see your page, but still wants to consume its content? First, how do they do that? They can't use the mouse, they use something called a screen reader . You don't have to imagine that. You can try one now: Google provides the free ChromeVox Chrome Extension . Accessibility must also take care of allowing tools to easily select elements or navigate through the pages.

Web pages and Web apps are not always built with accessibility as one of their first goals, and maybe version 1 is released not accessible but it's possible to make a web page accessible after the fact. Sooner is better, but it's never too late.

It's important and in my country, websites built by the government or other public organizations must be accessible.

What does this mean to make an HTML accessible? Let me illustrate the main things you need to think about.

Note: there are several other things to take care about, which might go in the CSS topic, like colors, contrast and fonts. Or how to make SVG images accessible . I don't talk about them here.

Use semantic HTML

Semantic HTML is very important and it's one of the main things you need to take care of. Let me illustrate a few common scenarios.

It's important to use the correct structure for heading tags. The most important is h1 , and you use higher numbers for less important ones, but all the same-level headings should have the same meaning (think about it like a tree structure)

Use strong and em instead of b and i . Visually they look the same, but the first 2 have more meaning associated with them. b and i are more visual elements.

Lists are important. A screen reader can detect a list and provide an overview, then let the user choose to get into the list or not.

A table should have a caption tag that describes its content:

Use alt attributes for images

All images must have an alt tag describing the image content. It's not just a good practice, it's required by the HTML standard and your HTML without it is not validated.

It's also good for search engines, if that's an incentive for you to add it.

Use the role attribute

The role attribute lets you assign specific roles to the various elements in your page.

You can assign lots of different roles: complementary, list, listitem, main, navigation, region, tab, alert, application, article, banner, button, cell, checkbox, contentinfo, dialog, document, feed, figure, form, grid, gridcell, heading, img, listbox, row, rowgroup, search, switch, table, tabpanel, textbox, timer.

It's a lot and for the full reference of each of them I give you this MDN link . But you don't need to assign a role to every element in the page. Screen readers can infer from the HTML tag in most cases. For example you don't need to add a role tag to semantic tags like nav , button , form .

Let's take the nav tag example. You can use it to define the page navigation like this:

If you were forced to use a div tag instead of nav , you'd use the navigation role:

So here you got a practical example: role is used to assign a meaningful value when the tag does not convey the meaning already.

Use the tabindex attribute

The tabindex attribute allows you to change the order of how pressing the Tab key selects "selectable" elements. By defaults only links and form elements are "selectable" by navigation using the Tab key (and you don't need to set tabindex on them).

Adding tabindex="0" makes an element selectable:

Using tabindex="-1" instead removes an element from this tab-based navigation, and it can be pretty useful.

Use the aria attributes

ARIA is an acronym that means Accessible Rich Internet Applications and defines semantics that can be applied to elements.

This attribute is used to add a string to describe an element.

I use this attribute on my blog sidebar, where I have an input box for search without an explicit label, as it has a placeholder attribute.

aria-labelledby

This attribute sets a correlation between the current element and the one that labels it.

If you know how an input element can be associated to a label element, that's similar.

We pass the item id that describes the current element.

aria-describedby

This attribute lets us associate an element with another element that serves as description.

Use aria-hidden to hide content

I like a minimalistic design in my sites. My blog for example is mostly just content, with some links in the sidebar. But some things in the sidebar are just visual elements that don't add up to the experience of a person that can't see the page. Like my logo picture, or the dark/bright theme selector.

Adding the aria-hidden="true" attribute will tell screen readers to ignore that element.

HTML basics

  • Overview: Getting started with the web

HTML ( H yper T ext M arkup L anguage) is the code that is used to structure a web page and its content. For example, content could be structured within a set of paragraphs, a list of bulleted points, or using images and data tables. As the title suggests, this article will give you a basic understanding of HTML and its functions.

So what is HTML?

HTML is a markup language that defines the structure of your content. HTML consists of a series of elements , which you use to enclose, or wrap, different parts of the content to make it appear a certain way, or act a certain way. The enclosing tags can make a word or image hyperlink to somewhere else, can italicize words, can make the font bigger or smaller, and so on. For example, take the following line of content:

If we wanted the line to stand by itself, we could specify that it is a paragraph by enclosing it in paragraph tags:

Anatomy of an HTML element

Let's explore this paragraph element a bit further.

paragraph element including opening tag, content reading 'my cat is very grumpy', and a closing tag

The main parts of our element are as follows:

  • The opening tag: This consists of the name of the element (in this case, p), wrapped in opening and closing angle brackets . This states where the element begins or starts to take effect — in this case where the paragraph begins.
  • The closing tag: This is the same as the opening tag, except that it includes a forward slash before the element name. This states where the element ends — in this case where the paragraph ends. Failing to add a closing tag is one of the standard beginner errors and can lead to strange results.
  • The content: This is the content of the element, which in this case, is just text.
  • The element: The opening tag, the closing tag, and the content together comprise the element.

Elements can also have attributes that look like the following:

Paragraph opening tag with a class attribute highlighted: class=editor-note

Attributes contain extra information about the element that you don't want to appear in the actual content. Here, class is the attribute name and editor-note is the attribute value . The class attribute allows you to give the element a non-unique identifier that can be used to target it (and any other elements with the same class value) with style information and other things. Some attributes have no value, such as required .

Attributes that set a value always have:

  • A space between it and the element name (or the previous attribute, if the element already has one or more attributes).
  • The attribute name followed by an equal sign.
  • The attribute value wrapped by opening and closing quotation marks.

Note: Simple attribute values that don't contain ASCII whitespace (or any of the characters " ' ` = < > ) can remain unquoted, but it is recommended that you quote all attribute values, as it makes the code more consistent and understandable.

Nesting elements

You can put elements inside other elements too — this is called nesting . If we wanted to state that our cat is very grumpy, we could wrap the word "very" in a <strong> element, which means that the word is to be strongly emphasized:

You do however need to make sure that your elements are properly nested. In the example above, we opened the <p> element first, then the <strong> element; therefore, we have to close the <strong> element first, then the <p> element. The following is incorrect:

The elements have to open and close correctly so that they are clearly inside or outside one another. If they overlap as shown above, then your web browser will try to make the best guess at what you were trying to say, which can lead to unexpected results. So don't do it!

Void elements

Some elements have no content and are called void elements . Take the <img> element that we already have in our HTML page:

This contains two attributes, but there is no closing </img> tag and no inner content. This is because an image element doesn't wrap content to affect it. Its purpose is to embed an image in the HTML page in the place it appears.

Anatomy of an HTML document

That wraps up the basics of individual HTML elements, but they aren't handy on their own. Now we'll look at how individual elements are combined to form an entire HTML page. Let's revisit the code we put into our index.html example (which we first met in the Dealing with files article):

Here, we have the following:

  • <!DOCTYPE html> — doctype . It is a required preamble. In the mists of time, when HTML was young (around 1991/92), doctypes were meant to act as links to a set of rules that the HTML page had to follow to be considered good HTML, which could mean automatic error checking and other useful things. However, these days, they don't do much and are basically just needed to make sure your document behaves correctly. That's all you need to know for now.
  • <html></html> — the <html> element. This element wraps all the content on the entire page and is sometimes known as the root element. It also includes the lang attribute, setting the primary language of the document.
  • <head></head> — the <head> element. This element acts as a container for all the stuff you want to include on the HTML page that isn't the content you are showing to your page's viewers. This includes things like keywords and a page description that you want to appear in search results, CSS to style our content, character set declarations, and more.
  • <meta charset="utf-8"> — This element sets the character set your document should use to UTF-8 which includes most characters from the vast majority of written languages. Essentially, it can now handle any textual content you might put on it. There is no reason not to set this, and it can help avoid some problems later on.
  • <meta name="viewport" content="width=device-width"> — This viewport element ensures the page renders at the width of viewport, preventing mobile browsers from rendering pages wider than the viewport and then shrinking them down.
  • <title></title> — the <title> element. This sets the title of your page, which is the title that appears in the browser tab the page is loaded in. It is also used to describe the page when you bookmark/favorite it.
  • <body></body> — the <body> element. This contains all the content that you want to show to web users when they visit your page, whether that's text, images, videos, games, playable audio tracks, or whatever else.

Let's turn our attention to the <img> element again:

As we said before, it embeds an image into our page in the position it appears. It does this via the src (source) attribute, which contains the path to our image file.

We have also included an alt (alternative) attribute. In the alt attribute , you specify descriptive text for users who cannot see the image, possibly because of the following reasons:

  • They are visually impaired. Users with significant visual impairments often use tools called screen readers to read out the alt text to them.
  • Something has gone wrong causing the image not to display. For example, try deliberately changing the path inside your src attribute to make it incorrect. If you save and reload the page, you should see something like this in place of the image:

The words: my test image

The keywords for alt text are "descriptive text". The alt text you write should provide the reader with enough information to have a good idea of what the image conveys. In this example, our current text of "My test image" is no good at all. A much better alternative for our Firefox logo would be "The Firefox logo: a flaming fox surrounding the Earth."

Try coming up with some better alt text for your image now.

Note: Find out more about accessibility in our accessibility learning module .

Marking up text

This section will cover some essential HTML elements you'll use for marking up the text.

Heading elements allow you to specify that certain parts of your content are headings — or subheadings. In the same way that a book has the main title, chapter titles, and subtitles, an HTML document can too. HTML contains 6 heading levels, <h1> - <h6> , although you'll commonly only use 3 to 4 at most:

Note: Anything in HTML between <!-- and --> is an HTML comment . The browser ignores comments as it renders the code. In other words, they are not visible on the page - just in the code. HTML comments are a way for you to write helpful notes about your code or logic.

Now try adding a suitable title to your HTML page just above your <img> element.

Note: You'll see that your heading level 1 has an implicit style. Don't use heading elements to make text bigger or bold, because they are used for accessibility and other reasons such as SEO . Try to create a meaningful sequence of headings on your pages, without skipping levels.

As explained above, <p> elements are for containing paragraphs of text; you'll use these frequently when marking up regular text content:

Add your sample text (you should have it from What will your website look like? ) into one or a few paragraphs, placed directly below your <img> element.

A lot of the web's content is lists and HTML has special elements for these. Marking up lists always consists of at least 2 elements. The most common list types are ordered and unordered lists:

  • Unordered lists are for lists where the order of the items doesn't matter, such as a shopping list. These are wrapped in a <ul> element.
  • Ordered lists are for lists where the order of the items does matter, such as a recipe. These are wrapped in an <ol> element.

Each item inside the lists is put inside an <li> (list item) element.

For example, if we wanted to turn the part of the following paragraph fragment into a list

We could modify the markup to this

Try adding an ordered or unordered list to your example page.

Links are very important — they are what makes the web a web! To add a link, we need to use a simple element — <a> — "a" being the short form for "anchor". To make text within your paragraph into a link, follow these steps:

  • Choose some text. We chose the text "Mozilla Manifesto".
  • Wrap the text in an <a> element, as shown below: html < a > Mozilla Manifesto </ a >
  • Give the <a> element an href attribute, as shown below: html < a href = " " > Mozilla Manifesto </ a >
  • Fill in the value of this attribute with the web address that you want the link to point to: html < a href = " https://www.mozilla.org/en-US/about/manifesto/ " > Mozilla Manifesto </ a >

You might get unexpected results if you omit the https:// or http:// part, called the protocol , at the beginning of the web address. After making a link, click it to make sure it is sending you where you wanted it to.

Note: href might appear like a rather obscure choice for an attribute name at first. If you are having trouble remembering it, remember that it stands for h ypertext ref erence .

Add a link to your page now, if you haven't already done so.

If you have followed all the instructions in this article, you should end up with a page that looks like the one below (you can also view it here ):

A web page screenshot showing a Firefox logo, a heading saying Mozilla is cool, and two paragraphs of filler text

If you get stuck, you can always compare your work with our finished example code on GitHub.

Here, we have only really scratched the surface of HTML. To find out more, go to our Learning HTML topic.

White Sox Designate Jose Rodriguez For Assignment

By Steve Adams | April 4, 2024 at 10:30am CDT

The White Sox have designated infielder Jose Rodriguez for assignment, as first reported by Francys Romero . Romero suggests that Rodriguez will be put on waivers, though Sox Machine’s James Fegan indicates that the organization will first seek a potential trade partner. Presumably, Rodriguez’s DFA will clear the way for right-hander Mike Clevinger to return to the Sox. Clevinger agreed to a one-year deal to return to Chicago earlier in the week.

Rodriguez, 22, appeared in one game with the White Sox in 2023 — his lone MLB appearance. He entered that game as a pinch-runner and came around to score, but he’s still awaiting his first major league plate appearance. He split the 2023 season between Double-A Birmingham and Triple-A Charlotte, batting a combined .262/.292/.437 with 21 home runs, 19 doubles, 31 steals (in 40 tries), a 21.9% strikeout rate and just a 4.1% walk rate.

Baseball America ranked Rodriguez ninth among White Sox farmhands heading into the 2023 season — a solid review on the back of a 2022 campaign in which he hit .280/.340/.430 in a full season of Double-A ball. His stock has dropped off considerably since that time, due in no small part to last year’s pedestrian offensive output and anemic walk rate. He’s regarded as a capable defender up the middle, though BA notes that he can at times be “too nonchalant” on defense, leading to some avoidable miscues.

Rodriguez is in the second of his three minor league option years. He’s played primarily in the middle infield but also has 184 innings of experience at third base. He’s a right-handed hitter with above-average speed, at least average power and some defensive versatility. All of that could hold appeal to another club seeking infield depth, even if there are still some refinements that need to be made in his free-swinging approach. The Sox will have a week to trade Rodriguez or attempt to pass him through outright waivers.

Did I miss something? His minor league numbers look rather good and he’s only 23. I would imagine a trade for him may be somewhat significant.

This applys to the 40 man roster not the 26 man roster. José was called up last year as an emergency depth piece, so basically service time ruling.

Did I miss something? Why would a rebuilding team like the White Sox be getting rid of anyone with any potential? Also if he is in the “second of three option years” why not just send him down to AAA?

17 mins ago

The option years are the service time management. Jose was called up due to lack of depth from last season as an emergency piece.

Somebody should claim him former top prospect with good minor league numbers. Considering the White Sox can’t develop talent definitely worth a risk to see if he’s still got untapped potential

Their player development benefits their pitchers not their hitters.

White Sox hate him for some reason. Good combo of pop/speed and even when they were forced to call him up last year they didn’t give him an AB. Looking forward to seeing where he goes and thrives.

CMS Finalizes Payment Updates for 2025 Medicare Advantage and Medicare Part D Programs

Finalized policies will continue to ensure the strength and stability of Medicare Advantage and Medicare Part D programs

Today, the Centers for Medicare & Medicaid Services (CMS) finalized the Calendar Year (CY) 2025 Rate Announcement for the Medicare Advantage (MA) and Medicare Part D Prescription Drug (Part D) Programs that updates payment policies for these programs and ensures payment accuracy. The Rate Announcement complements policies in the CY 2025 MA and Part D proposed rule that would strengthen protections for the millions of people who rely on MA and Medicare Part D prescription drug coverage, which will be finalized in the coming days. Under this CY 2025 Rate Announcement, payments from the government to MA plans are expected to increase on average by 3.70 percent, or over $16 billion, from 2024 to 2025. The federal government is projected to pay between $500 and $600 billion in Medicare Advantage payments to private health plans in 2025.

CMS is also finalizing improvements to the structure of the Medicare Part D drug benefit for CY 2025 that will result in lower drug costs for millions of people with Medicare through the concurrent release of the Final CY 2025 Part D Redesign Program Instructions. Thanks to the Inflation Reduction Act, President Biden’s lower-cost prescription drug law, annual out-of-pocket costs will be capped at $2,000 for people with Medicare Part D in 2025, leading to even more savings for people with Medicare Part D in CY 2025.

“Thanks to the President's lower cost prescription drug law, the Inflation Reduction Act, millions of people with Medicare Part D will see even lower costs next year. Your out-of-pocket costs for prescription drugs will be limited to no more than $2,000, keeping more of your money in your pocket,” said HHS Secretary Xavier Becerra. “In addition to improving the Part D drug benefit, we are updating payments to Medicare managed care plans for people who rely on these plans. The Biden-Harris Administration will continue to work on lowering health care costs for all Americans, fulfilling a promise the President made.”

“CMS continues to take steps to maintain the stability of the Medicare Advantage and Part D prescription drug programs,” said CMS Administrator Chiquita Brooks-LaSure. “The finalized policies in the Rate Announcement and the Part D Redesign Program Instructions will make improvements to keep Medicare Advantage payments up-to-date and accurate, lower prescription drug costs, and ensure that people with Medicare have access to robust and affordable health care options.”

The Rate Announcement finalizes annual updates to MA payment growth rates and changes to the MA and Part D payment methodologies to improve payment accuracy. The finalized CY 2025 Rate Announcement incorporates the most recent available fee-for-service payment data through quarter 4 of 2023 and includes the continued phase-in of the updated MA risk adjustment model that was first implemented in 2024 and continued phase-in of updates to the calculation of growth rates related to medical education costs, as well as other technical improvements. Last year, CMS finalized CY 2024 technical and clinical updates to the MA risk adjustment model to keep it up-to-date and improve payment accuracy, as well as updates to the calculation of growth rates to better account for medical education costs. For 2024, MA offerings for people with Medicare remained stable—including premiums, supplemental benefits, and choice.

“We are also pleased to finalize guidance on the new $2,000 out-of-pocket cap for prescription drugs under Medicare Part D in 2025, which was enacted in the President’s prescription drug law. This new provision will provide meaningful additional cost savings and relief to enrollees who have been facing high and rising drug costs,” said CMS Deputy Administrator and Director of the Center for Medicare Meena Seshamani, MD, Ph.D.
