Take a look at jquerymobile.com Most of that is using html5 and css3.

>There are lots of demos showing off the graphical speed and capabilities of HTML5 in the latest browsers, but are there any good demos of forms for business apps? Since HTML5 can supposedly be used in place of Silverlight/Flash for RIA and maybe even replace desktop GUIs, it would be good to see some of that in action.
