CSS Challenge

This is a challenge for all you web designers and CSS experts/hackers.

Check out this design:

Each panel has a margin between the parent of 10 pixels in each side. The red panels are also spaced by 10 pixels with each other.

The challenge: Create the above design

Rules of engagement

• You need to create this design using CSS classes only
• Each panel can be a div or ASP.Net panel control
• The panel should adjust automatically when the window resizes. The white panel should always cover the browser content.
• You can not use CSS expressions or JavaScript.
• No scroll bars are shown.
• The margins between the panels will always be 10 pixels.

I tried to implement this design, but didn't succeeded to to so by using CSS only.

Take your shoot!
