I dont know why the overlay is not being hidden after I click

//problem: user gets to dead end when clidking image //solution: create an overlay with a large image - Lightbox

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

$overlay.append($image);

//add overlay

$("body").append($overlay); //an image //a caption

//caption a click event on a link to an image

$("#imageGallery a").click(function(event){ event.preventDefault(); var imageLocation = $(this).attr("href"); //update overlay with image linked in link

$image.attr("src", imageLocation)

//show the overlay

$image.show();

//get the childs alt attr

});

//when overlay is clicked

$overlay.click(function(){ //hide the function

$overlay.hide();

});

Hi! You haven't shown the overlay. I believe this line 

//show the overlay

$image.show();

should be in fact.

//show the overlay

$overlay.show();

You have appended the image to the overlay, so this will show the overlay with the image on it.

also, I think you are missing semicolons after the variable declarations. Also the quotations are off. You should use single quotes for the 'overlay' id.

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

should be

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