title: How to specify multiple classes that can match a given selector?
body: <p>I'm trying to practice DRY in my CSS (wink) and I'm stuck on how to solve this.</p>
  
  <p>How do I reduce this:</p>
  
  <pre><code>table.shipmentItemList TD.title,
  table.shipmentItemList TD.author,
  table.shipmentItemList TD.options {
      font-size: 1.0em;
      font-weight: normal;
  }
  </code></pre>
  
  <p>To something like this:</p>
  
  <pre><code>table.shipmentItemList TD.title, TD.author, TD.options {
      font-size: 1.0em;
      font-weight: normal;
  }
  </code></pre>
  
  <p>Or better yet this:</p>
  
  <pre><code>table.shipmentItemList TD .title, .author, .options {
      font-size: 1.0em;
      font-weight: normal;
  }
  </code></pre>
