It looks OK in most browsers (except netscape 4 because of CSS2's min-width attribute), but at a resolution of less than 800*600, the box at the bottom has the other boxes over it
This is because I positionned the bottom box with absolute coordinates in pixels...

So, what I'd like to do is position the bottom box just under the upper boxes, like 20 pixels below. Is there a way for this ? (sorry if my question isn't that clear)
