title: Centering a group of images using Masonry
body: <p>I am using Masonry.js on a group of images and trying to center the entire group. I have gotten the group to center when I specify the width of the container grid and set <code>margin:0 auto</code>, but would love to center it using a more fluid grid or percentages. (I realize I could use media queries to change the fixed width, but looking for a more seamless option.) </p>
  
  <p><a href="http://bit.ly/RyxVix" rel="nofollow">Here is an example</a> of the code with a fixed width which is centering just fine.</p>
  
  <p>And <a href="http://bit.ly/VKBnBP" rel="nofollow">here is an example</a> of the more fluid example that I am trying to center but <code>margin:0 auto</code> isn't working.</p>
