css centered layout

I need a css redesign of the layout of my website. The layout has to be 100% css and compatible with all webbrowsers. It wil be a centered layout (fixed width), with adspace on both sides. The ads have to "dissapear" if the browser decreases in size. Take a look at the current div and table based layout at: httt://[login to view URL] It has to be exactly like that only in css, and with adspace on both sides. Also added an image with explanations.
