title: How to make underlying div unclickable?
body: <p>I made overlay div with:</p>
  
  <pre><code>position: absolute; top: 0; left: 0; widht: 100%; height: 100%;
  </code></pre>
  
  <p>Basically I want this overlay div to cover my whole page. And it does what I need, but I also need underlying divs to be unclickable. They are indeed unclickable but only in FF, Safari and Chrome. in IE and Opera you can still click buttons that are underneath.</p>
  
  <p>Does anyone have any idea on how can I achieve this "unclickable underlying behaviour"?</p>
