I have a layout with a 100% height for the content area. The problem is that it makes an iframe work perfectly for 100% height, but I cannot get it to work for a regular div. Is there a way to make the height 100% for the div? The white area should be filled with a black area but it does not. Any help would be greatly appreciated.

It would work if you set the height of
.inner-contentto 100% too:
