Board Thread:Support Requests - Designing Your Wikia/@comment-24164655-20140404170235/@comment-24042083-20140406153924

The GTA wiki uses the simple trick with the background of the wiki, like you said. They took he image they wanted as background and put a grey rectangle on the right place. But since the Fluid Layout, that doesn't work with narrow screens like iPads when using CSS for the background. You can see this effect by making your window narrow enough and going to any wiki. At the GTA wiki, you'll see that the background stays. At your wiki, the background will become black (the colour you chose in the Theme Designer).
