Topic: Puzzling problem with background element...

I have a question regarding style modification that hopefully someone can enlighten me on. I have noticed that with a lot of styles, the main forum elements will be floating over a background frame. For some reason, I can't seem to find out where it is in the .css files. Here is a small screenshot to illustrate what I mean:

If, for example, I remove the page body's background pattern or change the color, it will have no effect on that solid white background frame. It's rather puzzling. Anyone have any ideas on how to remove it or change the color?

I have hunted through the .css, _cs.css and base.css for the color of that background frame and haven't been able to find it. It is pure white (FFFFFF), but altering every instance of white doesn't change its color. I've searched for FFF, white and FFFFFF, but to no avail. What am I missing here? There must be something obvious that I'm overlooking.

punwrap? class pun?
Those are the two possibilities I can think of tongue
