title: css for all tags of a class
body: <p>How can I specify css for all td tags of a table of a certain class?
  I tried this:</p>
  
  <pre><code>.myclass td {padding: 1px;}
  </code></pre>
  
  <p>But it doesn't work. The html is:</p>
  
  <pre><code>&lt;table class="myclass"&gt;&lt;tr&gt;&lt;td&gt;foo
  </code></pre>
