overlay does not show in chrome

My overlay does not appear when I click on the image..??

see .js

//Problem: user when clicking on image goes to a deadend...
//Solution: Create an overlay with the large image - lightbox...
var $overlay = $('<div id="overlay"></div>');
// Add overlay

$("body").append($overlay);
  // An image
  // A caption

//Capture the click event on a link to an image. 
$("#imageGallery a").click(function(event){
  event.preventDefault();
 var href = $(this).attr("href");
  console.log(href);

  //1.1 Show the overlay.
  //1.2 update overlay with the image linked in the link.
  //1.3 Get child's alt atribute and set caption.
});
 //3. When overlay is clicked
  //3.1 Hide the overlay

see style.css

/** Start Coding Here **/

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

Hi Jonathan,

You might have already found the bug yourself but here is an answer just in case : In the click event $overlay.show(); is missing.
