Keeping frame background

[manvbf]

I just have a question, don't know if this is possible using frames. I have a frameset up with three frames, a side menu, a top menu, and the content frame. I was just curious if it is possible to make it so the content frame always has the consistent background color, even when loading new content.

The problem I have been experiencing is that when I load a page upon opening the site, and I click on a button, the content frame flashes white, then goes to our background color. I tried to make the backgrund fixed with CSS, but it didn't work. Any other ways to work this out?? Any help would be greatly appreciated.
