title: Javascript: how can I tell if a <span> is broken over 2 lines?
body: <p>I display a bubble help for some short span elements. The bubbles are centered below that span and look great as long as the span isn't broken over two lines.</p>
  
  <p>Looks good:</p>
  
  <pre><code>tell &lt;span&gt;irregular: told, told&lt;/span&gt;
  </code></pre>
  
  <p>Looks bad:</p>
  
  <pre><code>tell &lt;span&gt;irregular: told,
  told&lt;/span&gt;
  </code></pre>
  
  <p>It looks bad, because the bubble isn't centered under the span anymore. Is there some way using JavaScript or jQuery to tell, if that span is broken over two lines?</p>
