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

You have a dropdown in the top menu where you can switch the css validation. It's called Cascading style sheet version for validation. If you can't see it right click on the menu and check Style sheet so it will show.
