Background question

[Rho Delta]

I made my background a repeating image that is off white. How can I use the same image in the white space between sidebar blocks and the main forum area as seen by my pointers in this image?

Basically I want all of the areas with red headers to appear to kind of float above the static off white background.

I hope this makes sense.

Nevermind I found it at the acp-style properties - content - background image box.

Gotta love how easy XF is!
