Make CSS 3.0 the Default in Visual Studio 2010 SP1 Web Update

I'm working on a HTML5 / CSS 3.0 / MVC 3 project in Visual Studio 2010. Every time I restar开发者_如何转开发t VS and then open a CSS file, it's always set to 'CSS 2.1'. Is there a way to tell VS I want to use CSS 3.0 always (or at least by default)?

BTW, I have looked under "Tools>Options>Text Editor>HTML" - no CSS options, default is HTML5. I have also looked under "Tools>Options>Text Editor>CSS" - no version option as far as I can see.

Thanks, Michael

I had a similar problem after SP1.
I had to specifically install the "CSS 3 Intellisense Schema" found here -->

Restart VS and it started remembering what I had set last. HTH

The default CSS schema is defined by the selected HTML schema, but there is no UI to change the CSS schema targeted by the HTML schema. You will have to do it manually by editing the appropriate HTML schema.

To have HTML 5 target CSS 3.0, edit

"\Microsoft Visual Studio 10.0\Common7\Packages\schemas\html\html_5.xsd"

and change vs:cssschema to "CSS 3.0".
