The reason your wiki doesn't have those lines of code is because they're customisations of standard wikinav code that exist at this wiki only. By default, every wiki starts out with no customisations — that is, MediaWiki:Common.css and MediaWiki:Wikia.css are blank. Any time you see code in these files, you're looking at something that the local admin team (or possibly, Wikia Staff working on behalf of the local team) have put in place.
