Help with layout

Greetings all. I’ve got a little layout problem.

I’m designing a 3 column layout in CSS, a main middle section and two flanking menus. The side menus are fixed width, the middle is liquid.

Within this middle section I need to display products (see attached image), I’m just wondering how I’d do this. The left and right products need to be exactly 50% width each to accomodate and liquid movement.


Someone please help me with this!!
