HTML5 is a markup language used for structuring and presenting content on the World Wide Web. It is the fifth and last major HTML version that is a World Wide Web Consortium (W3C) recommendation.

HTML5 was first released in a public-facing form on 22 January 2008, with a major update and "W3C Recommendation" status in October 2014. Its goals were to improve the language with support for the latest multimedia and other new features; to keep the language both easily readable by humans and consistently understood by computers and devices such as web browsers, parsers, etc., without XHTML's rigidity; and to remain backward-compatible with older software. HTML5 is intended to subsume not only HTML 4 but also XHTML 1 and DOM Level 2 HTML.

Declaring your web page as HTML5

We recommend that you declare a true DOCTYPE within your web page. Within the examples here, we've declared our applications as HTML5 using the simple HTML5 DOCTYPE as shown below:

<!DOCTYPE html>

Most current browsers will render content that is declared with this DOCTYPE in "standards mode" which means that your application should be more cross-browser compliant. The DOCTYPE is also designed to degrade gracefully; browsers that don't understand it will ignore it, and use "quirks mode" to display their content.

<noscript> Element

In this HTML5 page example, a <script> tag is placed within the <body> tag to reference a javascript file called examples.js. Following that is a <nonscript> tag that will display alternate content if the <script> tag does not run (ie: either the browser's scripting has been disabled or the script type is not supported).

<!doctype html>
<html>

<head>
<meta charset="UTF-8">
<title>noscript element example</title>
</head>

<body>
<h1>Heading 1</h1>
<p>This is a paragraph.</p>
<script src="/scripts/examples.js"></script>
<noscript>
  <p>This is a <a href="examples.html">this is alternate content link if scripting is disabled</a>.</p>
</noscript>
</body>

</html>
