FEHC (Fake Equal Height Columns) Research

Equal Height Columns

IE6 cannot do 100% height on an absolutely positioned element within a relative positioned element with no height defined in pixels. IE 5.5 did when I tested as long as the relative positioned element had a height of 1px set, the element expands anyway and then the absolutely positioned element can fill with 100% height.
