What is HTML5?

HTML5 Information

The previous version of HTML, HTML 4.01, came in 1999. The web has changed a lot since then.
HTML5 is still a work in progress. However, the major browsers support many of the new HTML5 elements and APIs.

How Did HTML5 Get Started?

HTML5 is a cooperation between the World Wide Web Consortium (W3C) and the Web Hypertext Application Technology Working Group (WHATWG).

WHATWG was working with web forms and applications, and W3C was working with XHTML 2.0. In 2006, they decided to cooperate and create a new version of HTML.

Some rules for HTML5 were established:

• New features should be based on HTML, CSS, DOM, and JavaScript
• Reduce the need for external plugins (like Flash)
