Is there a way to make a floating div tag take on the actual height it has from content

I have a floating div tag to the left and then another div tag that auto margins to the right. If I take 开发者_如何学Pythonout the contents of the right div the left div tag "overlaps" everything below it.

How could I go by fixing this so it doesn't overlap?!

I'll include a picture to show you how it overlaps.

"if I make the div that holds the floating div a certain height, it works fine, but I need it to adjust to the content rather then setting a height"

Have you tried a min-high of 1px mite work mite not
