问题
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
What is not clear to me is how to activate CSS 3 validation. I did find that switching HTML validation to HTML 5 causes CSS to be validated as CSS 3 (after installing CSS 3 Intellisense Schema).
However, I would have thought that the HTML level and the CSS level would be orthogonal.
Am I missing something, or does the HTML validation switch truly also control the CSS validation level?
回答1:
First, right click on the toolbar in VS2010 and enable 'Style Sheet'. Then once a CSS file is open and has focus you can change the target CSS validator from the drop down.
