Er, no. Don't validate the css against the html validator - they
aren't the same species. You validate the underlying html file
against the html validator. If that checks out, *and* your
associated css file validates against the css validator, then you are
good to go. It is the html file that needs the doctype, etc.
And yes, you really do need to validate both.
