title: what does <a class="none"> really mean?
body: <p>Im not sure if anyone can help me with this but I came across this piece of code while modifying a theme for a wordpress. What is the effect of class="none" in this ? There is no css pointing to this class anywhere.</p>
  
  <pre><code>&lt;a class="post-thumb none" id="thumb-165" href="" title=""&gt;
        &lt;span class="no-img" style="width:90px;height:90px"&gt;&lt;/span&gt;    
  &lt;/a&gt;
  </code></pre>
  
  <p>Thanks in advance.</p>
