title: margin-left and margin-right auto, can't centered
body: <p>I am not able to center my <code>&lt;div&gt;</code> with this css in IE:</p>
  
  <pre><code>height: 842px;
  width: 595px;
  margin-left: auto;
  margin-right: auto;
  </code></pre>
  
  <p>What could be the reason and how to solve it?</p>
