Recorded as CSS2.1 Issue 62: http://lists.w3.org/Archives/Public/www-style/2008Jun/0245.html I think we want Firefox's behavior here, as that is forwards-compatible. Proposal: Change 'ruleset' to 'stylesheet' in the @media grammar. State in 7.2.1 that "At-rules inside @media are invalid in CSS2.1 and must be ignored per 4.2 Rules for handling parsing errors." ~fantasai
