You can add a background on the chat in different ways, but you can do it like this: /* Chat Background */ .ChatWindow .WikiaPage { background:url('image url here') no-repeat fixed center; } Just add on the place of image url here the image. You have to add this code to the page Special:CSS on your wiki :)
