title: Grow height of parent div that contains floating nested divs
body: <p>I can’t seem to auto-grow my parent <code>div</code>’s height based on its floating child <code>div</code>s. All the children are floating, to take up space horizontally, and then wrapping to the next line. There can be a changing number of floating children, and the parent has to auto-size its height. (The parent <code>div</code> serves as a background for all the floating <code>div</code>s). There is also a second <code>div</code> below the parent <code>div</code> that needs to be pushed down, so that it is below the floating <code>div</code>s.</p>
  
  <p>It’s of major importance that the solution works in IE.</p>
