title: add a class to the li element or the a?
body: <p>I have a standard list of links:</p>
  
  <pre><code>&lt;li&gt;&lt;a href=""&gt;one&lt;/a&gt;&lt;/li&gt;
  &lt;li&gt;&lt;a href=""&gt;two&lt;/a&gt;&lt;/li&gt;
  </code></pre>
  
  <p>If I want to add an extra class to one of the list items, should I add the class to the <strong>li</strong> or the <strong>a</strong> element? What is best practice?</p>
  
  <p>Many thanks!</p>
