I know this is a problem for a lot of people but... I can't get the background to turn black :(

I am having a problem with getting the background to turn black when I click on the links :( I watched the video a dozen times and I looked at a lot of the questions but still nothing, I don't know what the problem is but if anyone cares to take a look and if you see anything wrong with the code I would really appreciate the feedback :) Even if someone can confirm the code works for them I will feel better about moving on :) Thank you all :)

Here is the jQuery code

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

var jOverLay = $('<div id="overlay"></div>');
//2. Add overlay
$("body").append(jOverLay);
  //2.1. Add an image
  //2.2. Add a caption

//1. Capture click even on a link to an image
$("#imageGallery a").click(function(event){
  //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
  event.preventDefault();
  var href= $(this).attr('href');
  jOverLay.show();
});


//3. When overlay is clicked, 
  //3.1 Hide the overlay

Here is the CSS

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 **/
#jOverLay {
  background:black;
  width: 100%;
  height: 100%;
  position: absolute;
  top:0;
  left:0;
}

And here is the HTML

<!DOCTYPE html>
<html>
<head>
    <link rel="stylesheet" href="css/style.css" type="text/css" media="screen" title="no title" charset="utf-8">
    <title>Image Gallery</title>

</html>

Thank you all very much :)

Oh! Also I already tried both "jOverLay.show();" and "$("jOverLay").show();" in the function code and in the code declaring the variable and no luck :(

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

Here you are creating a div with an ID overlay.

In your CSS you are selecting something with the id of jOverLay. You need to change one of the names so they match.

#jOverLay {
  background:black;
  width: 100%;
  height: 100%;
  position: absolute;
  top:0;
  left:0;
}

It looks like you're adding the ID to the div in div id="overlay" but in your CSS you have the ID #jOverLay instead of just #overlay.

Hi.

In your CSS change #jOverLay to the id you gave the element before appending it - that is - #overlay.

'<div id="overlay"></div>'
