The reason I didn't respond was because I am watching a show, and I am not watching the chat.

To answer your question, removing stuff via CSS is usually a Terms of Use violation if implanted on the wiki (MediaWiki:Common.css/MediaWiki:Wikia.css). If this is a user implantation (Special:MyPage/global.css/Special:MyPage/wikia.css/etc), it is allowed. You can't add CSS unto the page itself to have effects.
