title: parent div does not grow in height
body: <p>I'm having trouble getting a parent div to extend its height as its children grow (Freud? :-))</p>
  
  <p><a href="http://nimya.50webs.com/green-label/test_1.html" rel="noreferrer">sample page here</a></p>
  
  <p>the parent here being "main_bottom" which contains "main_mid" and its children.</p>
  
  <p>the structure is a little unusual because the text has to be <strong>within</strong> the rounded corners, which are large, so  i could not use the usual 'fixed top - then dynamic mid  -then  fixed bottom' routine.</p>
  
  <p>of course the horrible pink and red are only so that the children divs  dimensions are easy to see..</p>
  
  <p>any help will be highly appreciated</p>
  
  <p>have a nice day</p>
