title: Get the position of a div/span tag
body: <p>Can someone show me how to get the <code>top</code> &amp; <code>left</code> position of a <code>div</code> or <code>span</code> element when one is not specified?</p>
  <p>ie:</p>
  <pre><code>&lt;span id='11a' style='top:55px;' onmouseover=&quot;GetPos(this);&quot;&gt;stuff&lt;/span&gt;
  &lt;span id='12a' onmouseover=&quot;GetPos(this);&quot;&gt;stuff&lt;/span&gt;
  </code></pre>
  <p>In the above, if I do:</p>
  <pre><code>document.getElementById('11a').style.top
  </code></pre>
  <p>The value of <code>55px</code> is returned. However, if I try that for <code>span</code> '12a', then nothing gets returned.</p>
  <p>I have a bunch of <code>div</code>/<code>span</code>s on a page that I cannot specify the <code>top</code>/<code>left</code> properties for, but I need to display a <code>div</code> directly under that element.</p>
