flowing layouts good for all resolution.

[lord_havoc]

Here recently, I got a new monitor and realized that while I had coded my site for my resolution, my div was off to the left for people with larger screens. Well now I am am trying to fix this. I know how to center with percentages.. but that will stretch out my div when viewed at a larger screen. And in this case I cannot have that because I have an image for the top and bottom. Is there a way to center it w/o stretching it? Now if your using IE (And maybe I haven't checked it yet in Opera or Safari) you will see some places that need to be fixed. There is no need to point theses out, I am still working on that. But I felt this issue should be addressed first.

My site is http://cyanideperfection.net

My stylesheet it at http://cyanideperfection.net/styles/sleek.css

Please help if you can.
