Forum:Class=Hover

I'd like to implement hovering table (as seen here, at the bottom) in my wiki. So, I copied the code below /** Banner at main page **/ from here and pasted it on my wiki's Wikia.css. But it's not working. I'm sure I've messed up, so can someone please help me out? Thanks! Ryoga Godai (talk)  11:56, September 4, 2012 (UTC)
