title: Can a <span> be made into a clickable link?
body: <p>To make a span into a clickable link. </p>
  
  <p>I have made  a span that contains only a background image (as part of a Gilder/Levin image replacement technique) into a clickable link, and it seems to work fine -- but, so far, that is only on my own desktop computer, and on Chrome, Opera, and IE 11.  </p>
  
  <p>Is this viable?</p>
  
  <pre><code>&lt;div id="logo"&gt;
    &lt;a href="[absolute url]"&gt; 
      &lt;span&gt;&lt;/span&gt;
    &lt;/a&gt;
    &lt;h1&gt;page name&lt;/h1&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>It works on my computer, with Chrome, IE11 and Opera. Will it work universally?</p>
