title: How to lock focus in a specific div using javascript/jquery
body: <p>I am developping some kind of modal popup using jQuery and I have some problems with the focus.</p>
  
  <p>What happens right now, is that when I press the tab key, the focus goes to the controls hidden behind the popup.</p>
