JavaScript jQuery Basics (2014) Creating a Simple Lightbox Perform: Part 4

Lightbox/Overlay not working properly

Hi, I followed the lessons down to a 'T' earned the badges too, but i just can't seem to 'get rid' of the overlay when the page loads up. I get the opaque overlay background and i'm unable to click on any image. my jQuery and CSS code is below:

//Problem: User when clicking on image goes to a dead end
//Solution: Create an overlay with the large image - Lightbox

var $overlay = $('<div id="overlay"></div>');
var $image = $("<img>");
var $caption = $("<p></p>")
//An image to overlay

//Add overlay
  //A caption

//Capture the click event on a link to an image
$("#imageGallery a").click(function(event){
  var imageLocation = $(this).attr("href");
  //Update overlay with the image linked in the link
  $image.attr("src", imageLocation);

  //Show the overlay.
  var captionText = $(this).children("img").attr("alt");

  //Get child's alt attribute and set caption


//When overlay is clicked
  //Hide the overlay

#overlay {
  width: 100%;
  left: 0;


#overlay img {
  margin-top: 10%;

#overlay p {
  color: white;

Bola Ajayi - For code that's more than a few lines it's often best to throw it into codepen it's easier to debug a "working" demo.

Add display: none and z-index: 5 to #overlay in your css.

Thanks Andrew - that worked a treat! James - Didn't know, next time - I will do! :)
