title: How to adjust Bootstrap's container div to 100px off the left viewport edge?
body: <p>I'm using the Twitter Bootstrap fixed layout where the container <code>div</code> has:</p>
  
  <pre><code>margin-left: auto;
  margin-right: auto;
  </code></pre>
  
  <p>So it always stays in the center.</p>
  
  <p>What I want to do is position the container so that there is a 100px gap between the left browser window border and the container. When the window gets smaller I want the container move to border of the window.</p>
  
  <p>How can I achieve this?</p>
