Hello. I'd love to to build the homepage of my wikia in CSS. But I can't put a background image to a div. I have this result. https://i.goopics.net/nk54K.png

I tested in html with the same code, and I have the result I want to have: https://i.goopics.net/9YRK1.png

Does Wikia manage its background differently? How can I solve the problem? Here is the code:
