What is HTML5?

HTML5 Information

HTML5 will be the new standard for HTML.
The W3C HTML5 recommendation was released 28. October 2014.
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)
  • Better error handling
  • More markup to replace scripting
  • HTML5 should be device independent
  • The development process should be visible to the public
HTML5 Modules:
  • New Elements
  • New Attributes
  • Full CSS3 Support
  • Video and Audio
  • 2D/3D Graphics
  • Local Storage
  • Local SQL Database
  • Web Applications
HTML5 New Features:
  • The <canvas> element for 2D drawing
  • The <video> and <audio> elements for media playback
  • Support for local storage
  • New content-specific elements, like <article>, <footer>, <header>, <nav>, <section>
  • New form controls, like calendar, date, time, email, url, search

The WHATWG works on a number of technologies that  :
