In the new FandomDesktop theme, is it possible to set a background image for the whole page, instead of just the top area? Our wiki (Girl Genius) currently has a tiled background image that covers the whole page.
Is it possible to do this in the FandomDesktop theme? If so, can it be done through the new theme designer interface? If this is the case, where do I add a background image? I have been unable to figure it out on my own. If it cannot be done through the theme designer interface, can a tiled background image be added through customized CSS?
