Nested border layout in css?

I have this working fine: http://jsfiddle.net/uwcEw/ - a traditional border layout on css.

What I want to do is have another 5-region border layout within the "middle" of the border layout. Re-applying the same pattern from above I get this: http://jsfiddle.net/6bked/4/ (edited link), which does not work, clearly it is not relative to it's parent container, but i'm not sure how to fix this so i can apply this pattern as needed in a nested context.

Any help? Also if there's a better way to do this (Compass+Sass/blueprint/js layout) I'm open to suggestions.

I also wanted to make clear I only care about this working in modern browsers (Webkit, FF) mostly concerned with Webkit and I am not worried about users who don't have javascript enabled

I'm not exactly the biggest fan of fixed layouts, but if I understand correctly this should be what you're trying to do: http://jsfiddle.net/8Cq9A/.

The dimensions are relative to the browser window, even the nested set of div's. What you needed to do to fix your layout was adjust your inner dimensions taking that into account. For example if your outer left and right div's widths are set to 10% (meaning 10% of the width of the browser window) to split the center div into 2 equal halves, you'd set each of their widths to: (100% - 10% - 10%) / 2 = 40%.

Personally, I'd look into using floats: http://jsfiddle.net/Sf8Kp/. The issue you will run into here though, is if you're wanting equal height columns as seen in the link.

There are MANY articles floating around on how to tackle this though. A few good reads that have been around for a while: alistapart (1, 2), positioniseverything. Search around for faux columns and 3 column [liquid|elastic|equal height] layout.
