Wow! I didn't even know they were in the process of making IE10. It was a guess.

@Pecoes: Wikia does use gradients. For FF, Chrome & Safari. (can't speak for Opera). I'm looking at them right now. will work, (and should be added to Wikia's code), when more people, world wide, have downloaded the new IE10. :)
