fluid - fixed - fluid

Currently the width of my site is fixed at a value about 1000 and that will almost always display a horizontal scroll bar. How would i go about making the sides fluid with the center being a fixed value?

I found a few tutorials and templates that would work with 2 columns, one fixed and the other fluid, but all of these have one of the columns a set number of pixels from one side. I can't do that if both sides are to be fluid with a fixed center.

here is my current test:

The gray trees should shrink with the window...

Your container is currently 1198px wide.

How about instead using a container of width 824px and adding the gray trees as a centered background image of the body element?

Hello antipepsiinc,
Have a look at this - http://www.nopeople.com/nopepsi/

I changed a lot of things around. I don't like absolute positioning at all but I left it in because I lost the 100%height once and I didn't feel like messing with it.

It validates and looks right in IE7 and FF2. I didn't look at it in IE6 over on the wifes computer.
