HTML5 : The Revised Version Of HTML

HTML5 is a revised version of HTML standard. Its development is still under process. The difference between HTML5 and its immediate predecessors HTML4.01 and XHTML1.1 is that HTML5 has features like video playback and drag-and-drop which were missing in the earlier versions.
The origin of the specification dates back to June 2004 by the Web Hypertext Application Technology Working Group (WHATWG) under the name Web Applications1.0.In March 2010 WHATWG was ready with the draft standard state of the specification. The editor of HTML5 is Ian Hickson of Google,Inc.Also at this point of time the specification was ready in working draft state at W3C(World Wide Web Consortium).
HTML5 was the starting point of the group working upon the new HTML at W3C in 2007.On 22nd January 2008 this working group published the First Public Working Draft of HTML5. The specification is still under development and will remain to be so for years to come although some parts of it will be ready to be implemented in the browsers soon. It is being estimated that HTML5 will reach the final recommendation stage in late 2010.It will be recommended by W3C.  Ian Hickson is expecting HTML5 to reach the Candidate Recommendation stage in 2012.The specification will be recommended by W3C only if it has “100% complete and fully interoperable implementations”.

Some sections are already relatively stable and there are implementations that are already quite close to completion, and those features can be used today (e.g. ).

– WHAT Working Group, When will HTML5 be finished?

HTML5 employs inputs which ensure full exhaustion on the modern websites. Some of the inputs are semantic replacements of general functions of generic block (

) and the inline () elements. Some of elements from HTML4.01 have been deleted and some new ones have been added to HTML5 to make it more efficient. The syntax of HTML5 is not based on SGML although their markup is same. Along with markup specification. Scripting application programming interfaces (APIs) is also specified by HTML5.
The new APIs specified are:

•The canvas element for immediate mode 2Ddrawing.
•Offline web applications.
•Timed media playback
•Document editing.
•Drag and drop.
•Cross document messaging.
•Browser history management.

HTML5 will be efficient and flexible enough to handle incorrect syntax. It has been structured in such a way that the old browsers can safely ignore the constructs of HTML5.
