Why HTML5?

why developers gear up to HTML5 and incorporate it in current projects too??

here comes the answer.. 

1) Audio and Video integration in html5

• Flash was used by developers previously..Flash is buggy, requires plug-ins, has frequent updates and gobbles up power on mobile devices. Flash is going away on mobile devices-no more Embed or Object tags.

• html5 technology allows developers to flex their HTML, CSS and JavaScript skills instead of using Flash or Silverlight. The Video and Audio tags perform better, too, which results in smoother playbacks and better power consumption, not to mention playback across all platforms. Finally, built-in support for captions and subtitles makes adding video and audio elements to a website easier than ever before.

• Media elements in html5 comes as:

• Video: Used to render video content.
• Audio: Used to define sound content.
• Embed: Used to insert, or embed, some type of multimedia content.
• Track: Defines text tracks for video and audio tags.
• Canvas: Allows for rendering of games, graphs and other visual images on the fly.

rest of the answers follows in my future posts :):)
