I copied and pasted that code and it didn't change anything. I also tried importing Raleway into MediaWiki:Common.css and that didn't do anything, but that being said, the page indicated that I couldn't import fonts there. 

Do you have any other ideas? You can check out the MediaWiki:Common.css page here and the MediaWiki:Wikia.css page here.
