JavaScript jQuery Basics (2014) Creating a Simple Lightbox Perform: Part 2

When I change background: black to rgba: (0,0,0,0,7); I can't click on the images and the overlay won't work

App.js file :

//Problem: The user when clicking on image goes to a bad end //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"); $overlay.show(); //Show the Overlay //Update overlay with the image linked in the link //Get child's alt attribute and set caption


//When Overlay is clicked //Hide the overlay

CSS file:

CSS file:

body { font-family: sans-serif; background: #384047; } h1 { color: #fff; text-align: center }

ul { list-style:none; margin: 0 auto; padding: 0; display: block; max-width: 780px; text-align: center; } ul li { display: inline-block; padding: 8px; background:white; margin:10px; } ul li img { display: block; } a { text-decoration: none; } /** Start Coding Here **/

overlay {

background: rgba(0,0,0,0,7); width: 100%; height: 100%; position: absolute; top: 0; left: 0; }

It looks you used a common in your RGBA (0,0,0,0,7) however it should be a period between the 0 and 7 (0,0,0,0.7). That may be the problem!

I've tried to change it to periods but it's still not working :S

In your css you need to set #overlay to display: none;

when you click on an image your javascript will execute the .show(); function which what it does is it changes the css of #overlay to display: block;

Thanks, It´s working now :)
