I have a floated column on the left and a left floated main section
next to it. I have some left floated elements in the main section and
sometimes I want to clear an element so that the subsequent elements
will not be floated, but still remain floated next to the left hand
column. . However, when I add "clear:both" to an element in the main
section, it clears not only the other elements in the main section,
but the left hand column too. Everything form that point on is below
the bottom of the left hand column. How do I clear just the items in
the main section ?
