The body
and html
are 100%, the #content
container is 100%, but the child #newstiles
won't match the 100% height that I set. I can set a fixed height, which increases it beyond the auto height that it currently seems to use, but 100% does nothing.
I must be going mad, or missing something very obvious!
Try to add
height: 100%;
to your #content style. You only defined max-height and min-height.
Try to set the position to "absolute" on #newstiles. Then the height is 100%, but then you get some the ugly scrollbar as the total page height would be 100% + your header.
I suggest you remove the height and width, and replace them with position absolute, top: 120px (the size of your top navigation) and bottom: 0px.
Hope this was what you were looking for. :)
