lang="en-US"><header><h1>HTML: HyperText Markup Language</h1></header><div class="section-content"><p><strong>HTML</strong> (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 (<a href="/en-US/docs/Web/CSS">CSS</a>) or functionality/behavior (<a href="/en-US/docs/Web/JavaScript">JavaScript</a>).</p> <p>"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.</p> <p>HTML uses "markup" to annotate text, images, and other content for display in a Web browser. HTML markup includes special "elements" such as <a href="/en-US/docs/Web/HTML/Element/head"><code><head></code></a>, <a href="/en-US/docs/Web/HTML/Element/title"><code><title></code></a>, <a href="/en-US/docs/Web/HTML/Element/body"><code><body></code></a>, <a href="/en-US/docs/Web/HTML/Element/header"><code><header></code></a>, <a href="/en-US/docs/Web/HTML/Element/footer"><code><footer></code></a>, <a href="/en-US/docs/Web/HTML/Element/article"><code><article></code></a>, <a href="/en-US/docs/Web/HTML/Element/section"><code><section></code></a>, <a href="/en-US/docs/Web/HTML/Element/p"><code><p></code></a>, <a href="/en-US/docs/Web/HTML/Element/div"><code><div></code></a>, <a href="/en-US/docs/Web/HTML/Element/span"><code><span></code></a>, <a href="/en-US/docs/Web/HTML/Element/img"><code><img></code></a>, <a href="/en-US/docs/Web/HTML/Element/aside"><code><aside></code></a>, <a href="/en-US/docs/Web/HTML/Element/audio"><code><audio></code></a>, <a href="/en-US/docs/Web/HTML/Element/canvas"><code><canvas></code></a>, <a href="/en-US/docs/Web/HTML/Element/datalist"><code><datalist></code></a>, <a href="/en-US/docs/Web/HTML/Element/details"><code><details></code></a>, <a href="/en-US/docs/Web/HTML/Element/embed"><code><embed></code></a>, <a href="/en-US/docs/Web/HTML/Element/nav"><code><nav></code></a>, <a href="/en-US/docs/Web/HTML/Element/search"><code><search></code></a>, <a href="/en-US/docs/Web/HTML/Element/output"><code><output></code></a>, <a href="/en-US/docs/Web/HTML/Element/progress"><code><progress></code></a>, <a href="/en-US/docs/Web/HTML/Element/video"><code><video></code></a>, <a href="/en-US/docs/Web/HTML/Element/ul"><code><ul></code></a>, <a href="/en-US/docs/Web/HTML/Element/ol"><code><ol></code></a>, <a href="/en-US/docs/Web/HTML/Element/li"><code><li></code></a> and many others.</p> <p>An HTML element is set off from other text in a document by "tags", which consist of the element name surrounded by <code><</code> and <code>></code>. 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 <code><title></code> tag can be written as <code><Title></code>, <code><TITLE></code>, or in any other way. However, the convention and recommended practice is to write tags in lowercase.</p> <p>The articles below can help you learn more about HTML.</p></div><section aria-labelledby="key_resources"><h2 id="key_resources"><a href="#key_resources">Key resources</a></h2><div class="section-content"><dl> <dt id="html_introduction"><a href="#html_introduction">HTML Introduction</a></dt> <dd> <p>If you're new to web development, be sure to read our <a href="/en-US/docs/Learn/Getting_started_with_the_web/HTML_basics">HTML Basics</a> article to learn what HTML is and how to use it.</p> </dd> <dt id="html_tutorials"><a href="#html_tutorials">HTML Tutorials</a></dt> <dd> <p>For articles about how to use HTML, as well as tutorials and complete examples, check out our <a href="/en-US/docs/Learn/HTML">HTML Learning Area</a>.</p> </dd> <dt id="html_reference"><a href="#html_reference">HTML Reference</a></dt> <dd> <p>In our extensive <a href="/en-US/docs/Web/HTML/Reference">HTML reference</a> section, you'll find the details about every element and attribute in HTML.</p> </dd> </dl></div></section><section aria-labelledby="beginners_tutorials"><h2 id="beginners_tutorials"><a href="#beginners_tutorials">Beginner's tutorials</a></h2><div class="section-content"><p>Our <a href="/en-US/docs/Learn/HTML">HTML Learning Area</a> features multiple modules that teach HTML from the ground up — no previous knowledge required.</p> <dl> <dt id="introduction_to_html"><a href="/en-US/docs/Learn/HTML/Introduction_to_HTML">Introduction to HTML</a></dt> <dd> <p>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.</p> </dd> <dt id="multimedia_and_embedding"><a href="/en-US/docs/Learn/HTML/Multimedia_and_embedding">Multimedia and embedding</a></dt> <dd> <p>This module explores how to use HTML to include multimedia in your web pages, including the different ways that images can be included, and how to embed video, audio, and even entire other webpages.</p> </dd> <dt id="html_tables"><a href="/en-US/docs/Learn/HTML/Tables">HTML tables</a></dt> <dd> <p>Representing tabular data on a webpage in an understandable, accessible way can be a challenge.
