Center page content margin: 0 auto; not working? : <p>I am trying to centre the content on this page <a href="http://www.seoweather.com/google-cache-search/" rel="nofollow noreferrer">http://www.seoweather.com/google-cache-search/</a></p>

<p>I tried adding the below but no luck.</p>

<pre><code>.container_24 .grid_24 { margin: 0 auto; }
</code></pre>

<p>As I understand, if the margins are set to margin: 0 auto; and the width is defined which it is as per below, it should center?</p>

<pre><code>.container_24 .grid_24 { width: 960px; }
</code></pre>

<p>I'm obviously going wrong somewhere, please enlighten me :)</p>
