Hi! I'm having a major issue with collapsing with CSS. I'm trying to collapse a section on a template I made but it is not collapsing. This is the template: http://austinallyroleplaying.wikia.com/wiki/Template:Tweeter1 I'm trying to collapse the "Following" and "Followers" section so that "" and "" do not show.

This is the coding I'm using to collapse it:

Is there something I have to add to a MediaWiki to do this because collapsing is working on other wikis (Camp Half Blood Roleplaying). Please help me! Thank you a lot! I really appreciate this! :)
