Add to the bottom of your MediaWiki:Wikia.css (let's suppose that for this example you want it to be red): body.ChatWindow { background: red !important; } If you want an a background image, use instead: body.ChatWindow { background: url('FULLURL') top !important; } And repalce FULLURL with the image URL. If the image is smaller than the window, and you don't want it to repeat itself, use instead: body.ChatWindow { background: url('FULLURL') top no-repeat !important; }
