title: Round thead corners in Firefox with CSS
body: <p>I would actually want to round thead's corners within a table. It doesn't seems to be possible as far as I'm concerned. I have tried almost everything but I couldn't get it work.</p>
  
  <p>The problem is that I basically have a table which's thead has a particual color, let's say black, and I'd like to give it a little rounding by rounding it's corners.</p>
  
  <p>Can anyone please tell me how is it possible?</p>
  
  <p>Here is the jsFiddle I have tried so far: </p>
  
  <p>HTML:</p>
  
  <pre><code>    &lt;table&gt;
      &lt;thead&gt;
          &lt;tr&gt;
              &lt;th&gt;First&lt;/th&gt;
              &lt;th&gt;Second&lt;/th&gt;
              &lt;th&gt;Third&lt;/th&gt;
          &lt;/tr&gt;
      &lt;/thead&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>CSS:</p>
  
  <pre><code>table {
      margin: 0px auto;
      clear: both;
      width: 100%;
      border: 1px solid white;
     -moz-border-radius: 3px;
      -webkit-border-radius: 3px;
      border-radius: 3px;
      color: white;
  }
  
  table thead {
      background: black;
      -moz-border-radius: 3px;
      -webkit-border-radius: 3px;
      border-radius: 3px;
  }
  </code></pre>
