More About HTML5

What is interesting is that WHATWG (the Web Hypertext Application Technology Group) started the movement toward HTML5 by developping HTML with new features consistent with how the web was being used. The major browser vendors begain supporting this movement and finally the W3C announced that they would support WHATWG.

HTML5 can be used for animation and interactivity if it is combined with CSS3 and Javascript. There is a trend of using HTML5 to replace the functionality of Flash in webpages.
