I just started using css and I am using xhtml 1 trasitional. I already validated my codes but I have an external css file. One of the books I am reading for css help says to validate my css codes but its not validating. Is there a standard setup I need to have it in so that the w3c validator can read it? I have searched through their site and haven't seen anything like. I would appreciate all comments... the external css file works and everything but I just want to see it validated....
