set size of div based on floating element inside

I am building a small html web page. In my web page I've got a div, inside it I've got a floating div. I'd like to get the height of my wrapper div to be similar to that of my floating div. How can this be done in css \ html?

From your question, I'm guessing the problem is that your containing div looks like this:

The solution is to "clear your floats".

An easy way to do this is to apply overflow: hidden to your containing div, like this:

Thirtydot is correct, you should clear your floats, but I would recommend you use the clearfix method instead. Using overflow:hidden will cause unintended problems with CSS properties that extend past the boundaries of a container.
