title: Center element with class
body: <p>I have the follow problem, that the tripadviser element not center inside the div:</p>
  
  <p><strong>HTML</strong></p>
  
  <pre><code>&lt;div class="box"&gt;
     &lt;div class="center"&gt;
        &lt;div id="TA_rated652" class="TA_rated"&gt;
           &lt;ul id="aZ2UznGh" class="TA_links ztx26p"&gt;
              &lt;li id="FyjgLOVkx" class="tmeRQwSrMol"&gt;&lt;a href="http://www.tripadvisor.de/Attraction_Review-g293918-d1942956-Reviews-The_Dive_Academy-Koh_Samui_Surat_Thani_Province.html" class="center"&gt;The Dive Academy&lt;/a&gt;&lt;/li&gt;
           &lt;/ul&gt;
        &lt;/div&gt;
        &lt;script src="http://www.jscache.com/wejs?wtype=rated&amp;amp;uniq=652&amp;amp;locationId=1942956&amp;amp;lang=de"&gt;&lt;/script&gt;
     &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p><strong>CSS</strong></p>
  
  <pre><code>.block05 .center { 
      display:block;
      margin-left:auto;
      text-align:center;
   }
  </code></pre>
