The HTML we have been learning so far is  HTML4.01. HTML5 will be the new standard of HTML. HTML5 is a cooperation between the W3C and WHATWG(Web Hypertext Application Technology Working Group).A few differences between HTML5 and HTML 4.01 is listed below:

  • It is enough to give the doctype declaration in HTML5 as <!Doctype> rather than long SGML based declaration in HTML4.
  • Audio and video are integral part of HTML Specifications and can be used as tags eg:- <video>  </video>.
  • Vector graphics in HTML4 is possible using technologies such as VML,Silverlight ,Flash etc while it has been integrated in HTML5.
  • For applications that may require true Geolocation of user, we can make use of JS Geolocation API in HTML5 while such facilities are not available in HTML4.
  • In HTML4 Browser cache is used for temporary storage while in HTML5 Application cache, Web SQL database and web storage is available as client side storage.
  • In HTML4 web sockets are not available. Mechanisms like long polling and streaming are used instead. In HTML5 full duplex communication can be established with server using web sockets.
  • One more cool feature about HTML5 is the JS web worker API which allows Javascript to run in the background.
  • HTML5 is packed with new semantic elements like <header>, <footer> which is more easy and comfortable to use rather than our traditional div tag in HTML4.
Stay Tuned.
