Visual Studio 2010 SP1 is installed, still no support for CSS3 and HTML5

Question

I've downloaded the latest version of Visual Studio 2010's Service Pack 1 from here. However, after I extracted the files, installed the SP1, and restarted the whole OS, still I don't get support for CSS3 and HTML5 in VS2010.

Have you experienced the same problem? Anyone has any idea?

Update: HTML5 and CSS3 support is promised in these links (and of course, many more could be found):

1. Here
2. Here
3. And here

And also I've installed Web Standards Update for Microsoft Visual Studio 2010 SP1, but still no success.
