#overlay Lightbox set to 100% is invisible.

When I set #overlay width and height to 100% (of body which has default of 100%) it is invisible. The overlay is visible only when height and width is set to px. My question concerns my project (not the one from the video) but everything has been set accordingly.

var $overlay = $('<div id="overlay"></div>');

$(".div").click(function(event){
  event.preventDefault();

  $overlay.show();
});

CSS

body {
  background-color: #f3f3f3;
}

#overlay {
  background: rgba(0,0,0,0.7);
  width: 100%;
  height: 100%;
  position: absolute;
  top: 0;
  left: 0;
  display: none;
  text-align: center;
}

Instead of width and height 100% try instead setting right and bottom to 0

Thx for your response. Now the width is 100%, but the height is only 100% of the window size. When i scroll down there's no overlay.

I fixed it setting position to FIXED instead of ABSOLUTE.
