It's not bad to add new contents, just remember to double check if a similar file was previously uploaded. As for ones with codes and classes, if you see  in what you copied, check mediawiki:Common.css or mediawiki:Wikia.css. If you can't see that class there, no matter what edit you do, it will not take effect.
