title: How do I get a div background image to scroll?
body: <p>I want the background image of a div (with id="library_tracks") to be repeated in both x and y directions and to scroll with the div. For whatever reason, the background is staying fixed. I imagine the solution is pretty straight forward... any ideas?</p>
  
  <p>Here's my CSS:</p>
  
  <pre><code>#library_tracks {
      overflow-y: scroll;
      height: 400px;
      border: thin solid #DADADA;
      background-image: url('../img/track_background.png');
      background-attachment: scroll;
  
  }
  </code></pre>
