title: :active pseudo-class doesn't work in mobile safari
body: <p>In Webkit on iPhone/iPad/iPod, specifying styling for an :active pseudo-class for an <code>&lt;a&gt;</code> tag doesn't trigger when you tap on the element. How can I get this to trigger? Example code:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;style&gt; 
  a:active { 
      background-color: red;
  }
  &lt;/style&gt;
  &lt;!-- snip --&gt;
  &lt;a href="#"&gt;Click me&lt;/a&gt;
  </code></pre>
