title: Centering iframe div
body: <p>When coding an iframe to resize with the screen I cannot center it. I tried all the responses from <a href="https://stackoverflow.com/questions/20583088/how-to-align-iframe-always-in-the-center">THIS</a> question but had no luck. Am I missing something obvious or is there no way to do this?</p>
  
  <p>HTML</p>
  
  <pre><code>&lt;div class="videoWrap"&gt;
      &lt;iframe src="http://www.youtube.com/embed/playlist?list=PLn0iVeY0xhgZvWDQ1K_6EChZe_4TL5zDZ"&gt;&lt;/iframe&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>CSS</p>
  
  <pre><code>.videoWrap {
      position: relative;
      padding-bottom: 56.25%; /* 16:9 */
      padding-top: 25px;
      height: 0;
  }
  .videoWrap iframe {
      position: absolute;
      top: 0;
      left: 0;
      width: 80%;
      height: 100%;
  }
  </code></pre>
