There is no problem with the CSS code. Presuming that you are using Oasis, the actual issue seems to be that code is not loading for Oasis skin as it is on MediaWiki:Common.css. For the most amount of wikis created before 2014, CSS within MediaWiki:Common.css does not work on Oasis but only for MonoBook, unless you request Wikia Staff to enable it on both skins. As you can see there, it works on MonoBook.
