title: extend div height to entire webpage
body: <p>Is there a way I can extend the height of a div to the entire webpage using css?</p>
  
  <p>I am not using </p>
  
  <pre><code>.height
   {
    height:100%;
    }
  </code></pre>
  
  <p>But this will only extend to the height of the contents inside the div. The div should cover the entire webpage even if there is just a 1 line worth of content inside it. </p>
