title: What's the :any-link pseudo-class for?
body: <p>I don't know if it's a part of any standard, but at least two major browsers have implemented it:</p>
  
  <ul>
  <li><code>:-webkit-any-link</code> in Chrome</li>
  <li><code>:-moz-any-link</code> in Firefox</li>
  </ul>
  
  <p>I can't find any documentation for it. I would like to know its purpose, browser support, and examples of usage.</p>
