title: Embarrasingly I can't get a div to pick up a background colour
body: <p>What I would like is to have the iframe cover 90% of the screen and add some buttons at the bottom, I need a background color on the div that covers the bottom 10% but I can't get the css to work. Where am I going wrong?</p>
  
  <pre><code>&lt;iframe src="http://tttdev.throughtheturnstile.com" style="width:100%; height:90%;position: absolute;" frameBorder="0"&gt;&lt;/iframe&gt;
  &lt;div style="clear:both"&gt;&lt;/div&gt;
  &lt;div style="position: absolute; bottom:0; background-color: black; height: 50px;"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>It seems to create the div, just not style it...</p>
