Background Color for MainWrapper Messed Up!!

[Whispers143]

Howdy friends, I am about to pull my hair out on this one! I want to modify the style sheet for mysite. All I want is a different background color for the back drop and white for the main content. I hope that makes sense At any rate, whenever I change the background image or background color it changes the entire background of the whole site. No matter how much I've tried to tweak it and change it... I will leave it at this mess it is now so that you can see the coding and the problem,but only for a couple of hours b/c it looks so tacky. So in closing... I want most outter background to be (black or an image) and the content (the meat and potatoes of the content & images) to be white. Please help
