HTML (HyperText Markup Language) is the most basic building block of the Web. It defines the meaning and structure of web content. Other technologies besides HTML are generally used to describe a web page's appearance/presentation (CSS) or functionality/behavior (JavaScript).
"Hypertext" refers to links that connect web pages to one another, either within a single website or between websites. Links are a fundamental aspect of the Web. By uploading content to the Internet and linking it to pages created by other people, you become an active participant in the World Wide Web.
HTML uses "markup" to annotate text, images, and other content for display in a Web browser. HTML markup includes special "elements" such as , , , , , , , , , , , , , , , , , , , , , , , , and many others.
An HTML element is set off from other text in a document by "tags", which consist of the element name surrounded by "<" and ">". The name of an element inside a tag is case-insensitive. That is, it can be written in uppercase, lowercase, or a mixture. For example, the tag can be written as , , or in any other way. However, the convention and recommended practice is to write tags in lowercase.
HTML Introduction
If you're new to web development, be sure to read our HTML Basics article to learn what HTML is and how to use it.

Our HTML Learning Area features multiple modules that teach HTML from the ground up — no previous knowledge required.
Introduction to HTML
This module sets the stage, getting you used to important concepts and syntax such as looking at applying HTML to text, how to create hyperlinks, and how to use HTML to structure a web page.

HTML tables
CORS enabled image
The crossorigin attribute, in combination with an appropriate CORS header, allows images defined by the element to be loaded from foreign origins and used in a element as if they were being loaded from the current origin.
CORS settings attributes
Some HTML elements that provide support for CORS, such as or , have a crossorigin attribute (crossOrigin property), which lets you configure the CORS requests for the element's fetched data.
Preloading content with rel="preload"
The preload value of the element's rel attribute allows you to write declarative fetch requests in your HTML , specifying resources that your pages will need very soon after loading, which you therefore want to start preloading early in the lifecycle of a page load, before the browser's main rendering machinery kicks in. This ensures that they are made available earlier and are less likely to block the page's first render, leading to performance improvements. This article provides a basic guide to how preload works.
HTML reference
HTML consists of elements, each of which may be modified by some number of attributes. HTML documents are connected to each other with links.

The MDN docs can def be a bit dry and overwhelming, especially starting out. I would still recommend them though, they are the gold standard in my mind. However MDN also has a series of GUIDES, that are extremely well done, easy to follow, and easy to reference back. Those in conjunction with the docs are, IMO, the best way to learn web ...
