how to get the css version

Question

How do i get the version of CSS that I am using?

Answer 1

Just an addition of what @Craig said.

In my .net 2.0 framework I have a property to show scroll bars. As I want just the vertical, I've added both properties and, if the browser that user is using support this new CSS 3.0 property (overflow-x), he will see just the vertical one.
