css floating beside fixed element
===

I need some help with CSS.

I want to create this structure:

I want to create a menu, center-fixed, with 960px; - that's quite simple..

On the same row as the menu, I want to create two div's: one from the left border of the monitor until the nearest of the centered-div from the midle, and another from the next of the centered until the right border of the monitor.

I will try to describe you using keys.

|__left_div__| |___fixed_centered_960px_div| |__right_div__|

The right and left divs will be fluid and will depends by the screen resolution.

Anyone can help me?

Thanks.
