<p><strong>HyperText Markup Language (<em>HTML</em>)</strong> is the language used to create web pages and other types of documents viewable in a browser. More precisely, HTML is the language that describes the structure and the semantic of a document. The content is tagged with HTML elements like <code><img></code>, <code><title></code>, <code><p></code>, <code><div></code>, …</p>
<p>HTML is an international standard whose specifications are maintained by the <a class="external" href="http://www.w3.org/">World Wide Web Consortium</a> and the <a href="http://www.whatwg.org/" title="http://www.whatwg.org/">WHATWG</a>.</p>
<p>HTML is considered a <em>living standard</em> and is technically under continuous development. That always-current version of the HTML specification is referred to as <strong>HTML5</strong>.</p>
