title: Jquery (or CSS) autoresize iframe to the bottom?
body: <p>i've no idea how i can set properties for an iframe that's positioned 300px from the top, but should reach ALWAYS the bottom!</p>
  
  <p>So at the moment i've set the height of the iframe to 500px. The height should dynamically change when i resize the browserwindow. The iframe should start 300px from the top and should always reach the bottom.</p>
  
  <p>I'm not much of an css expert.
  Any idea what i have to do?</p>
  
  <pre><code>    #frame {
   overflow:hidden;
   border:none;
   width:100%;
   height:500px;
   margin-top:300px;
  }
  </code></pre>
