With the third platform preview, we introduce support for the HTML5
Canvas element. As you know our approach for standards support is
informed both by developer feedback and real word usage patterns today,
along with where we see the web heading. Many web developers have asked
us to support this part of HTML5 and we definitely took this feedback
into account as we prioritized our work.
Like all of the graphics in IE9, canvas is hardware accelerated
through Windows and the GPU. Hardware accelerated canvas support in IE9
illustrates the power of native HTML5 in a browser. We’ve rebuilt the
browser to use the power of your whole PC to browse the web. These
extensive changes to IE9 mean websites can now take advantage of all the
hardware innovation in the PC industry.
Preview 3 completes the media landscape for modern websites with
hardware accelerated video, audio, and canvas. Developers now have a
comprehensive platform to build hardware accelerated HTML5 applications.
This is the first browser that uses hardware acceleration for
everything on the web page, on by default, available today for
developers to start using for their modern site development.
The third platform preview continues to support more of DOM and CSS3
standards that developers want. Examples here include DOM Traversal,
full DOM L2 and L3 events, getComputedStyle from DOM Style, CSS3 Values
and Units, and CSS3 multiple backgrounds.
