I would like to have multiple divs with margins and below them one that fills up the rest of the space provided by the fixed size parent div.
EDIT: I am sorry, I should have mentioned that the container divs size is fixed and should not change at all.
EDIT2: SOLUTION.
I had tried overflow: hidden but missunderstood it and put it on on the child element and not the parent.
Hope this is you want http://jsfiddle.net/FR5Ud/33/
