If you write HTML in a way that the page doesn't break when CSS is missing
(which should be the way to write it), you don't have a reason to want to
test this. "Please enable your CSS" is the same as "Your browser doesn't
support frames". It won't fare well in search engines, and it's plain
meaningless in browsers that don't have any CSS support.
I wouldn't even expect a typical visitor to know what "CSS" is. Unless it's
a technically knowledgeable user, then there's probably good reason CSS is
turned off in the first place.
