title: html div: opaque, but allowing click to reach element behind
body: <p>I want to make a flicking div (alternating display:none) in front (z order) of an element, but if the user clicks the element in the exact moment the div is appearing, the div receives the click, not the element.</p>
  
  <p>How can I make the div transparent to clicks? That is, can it ignore the clicks so that the onclick event always goes to the element behind the div?</p>
