visual studio 2010 - Is it possible to change CSS Validation scheme in VS2010

Question

I'm editing a simple CSS file in VS2010 and the editor seems to have a rather limited understanding of CSS, for example:

#my-rule {
     position:relative;
}

generates a warning: Validation(CSS 1.0): 'position' is not a known CSS property name

I'm guessing that there is an option some where to change the CSS validation to CSS 2.1 or some thing close, but can't for the life of me find it.

Answer 1

If you want to validate for CSS 3.0 in Visual Studio 2010, you need to install the Visual Studio 2010 Service Pack 1 and then install the "CSS 3 Intellisense Schema"

Then you will see "CSS 3.0" in the drop down that easwee mentioned.
