$overlay.show() does not work for me.. I had to use $("#overlay").show();

This would not work for me:

var $overlay = '<div id="overlay"></div>';
$("body").append($overlay);

$("#imageGallery a").click(function(event) {
event.preventDefault();
var href = $(this).attr("href");
console.log(href);
$overlay.show();
});

I had to change $overlay.show() to $("#overlay").show(); in order to get this to work.

My CSS:

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

:point_right: It looks like your top line is missing the part that creates a JQuery object from the string.

You probably meant to write:

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

I'm surprised that $("#overlay").show(); worked - it could be that you also forgot to remove the overlay div from the HTML.

var $overlay = $('<div id="overlay"></div>'); use this on the top your jquery but not this one you used in your code " var $overlay = '<div id="overlay"></div>';"
