Validate VS2010, HTML 5 and CSS 3

Question

I want to switch CSS validation in VS2010 SP1 from CSS 2.1 to CSS 3.

I came across this answer:

Is it possible to change CSS validation scheme in VS2010

It’s not clear to me how to activate CSS 3 validation. I found that switching HTML validation to HTML 5 causes CSS to validate as CSS 3 (after installing CSS 3 Intellisense Schema ).

However, I would think that the HTML level and CSS level would be orthogonal.

Am I missing something, or does the HTML validation switch really also control the level of CSS validation?

Answer 1

First, right-click on the toolbar in VS2010 and turn on the “Style Sheet”. Then, as soon as the CSS file is open and focused, you can change the target CSS validator from the drop-down list.
