title: Center Container for JQuery Packery?
body: <p>I use <a href="http://packery.metafizzy.co/" rel="nofollow">JQuery Packery</a> which works fine. </p>
  
  <p>The question that occurs to me is how can I center the item container on my page?</p>
  
  <pre><code>&lt;div id="container"&gt;
    &lt;div class="item"&gt;...&lt;/div&gt;
    &lt;div class="item w2"&gt;...&lt;/div&gt;
    &lt;div class="item"&gt;...&lt;/div&gt;
    ...
  &lt;/div&gt;
  </code></pre>
  
  <p>I tried css: </p>
  
  <pre><code>#container {
   marin: 0 auto;
  }
  </code></pre>
  
  <p>but this does not work.</p>
