jQuery overlay size problems

I am trying to integrate a lightbox into a personal project, and I am starting with an overlay. The problem is the overlay will not span the full height of the page.

Here's my code:

jQuery:

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

$("body").append($overlay);

$overlay.show();

css:

overlay{

background:rgba(0,0,0,0.7); width:100%; height:100%; position:absolute; top:0; left:0; display:none; }

Hi Ashley,

I have successfully integrated the lightbox project to my portfolio.

This var $overlay=$(''); is an empty Jquery object that you are creating, and in consequence you are appending "nothing" to your body tag, it should be:

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