title: background not accessible with javascript
body: <ol>
  <li>I want to make whole background of web-page unclickable with some gray color behind</li>
  <li>To pop some yes/no decision dialog on front</li>
  <li>If yes is clicked then redirect to other page (same with no)</li>
  </ol>
  
  <p>how to do that?</p>
