title: How can I add a vertical scrollbar to my div automatically?
body: <p>I want to add a vertical scrollbar to my <code>&lt;div&gt;</code>. I've tried <code>overflow: auto</code>, but it is not working. I've tested my code in Firefox and Chrome. </p>
  
  <p>I'm pasting the div style code here:</p>
  
  <pre><code>float: left;
  width: 1000px;
  overflow: auto;
  </code></pre>
