title: Align iframe in internet explorer
body: <p>I have css like this </p>
  
  <pre><code>.iframe1 {
  position: fixed; 
  height: 100%;
  width: 100%;
  padding-left: 160px;
  padding-right: 160px;
  text-align: center;
  margin-left: auto;
  margin-right: auto;
  }
  </code></pre>
  
  <p>This aligns center in all browsers except IE7. I know it's an old browser but my client insists on it. Instead of aligning center in IE7 it only pads 160px to the left and not center. </p>
  
  <p>How do I center this in IE? </p>
  
  <p>Thanks</p>
