dont understand why this code isnt working ?

everything seems to be working except for the prevent default ? it still loading the image.

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

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

Hi simon lavery, I've updated your question so the code is correctly highlighted.

As for your question, you might need to share some more code surrounding just what you have there. (Such as the HTML for the links you're binding event handlers to, etc).

Note that you're also setting the variable href in that function, but not using it for anything.

I had the same issue. My problem was that even though i've added the id "imageGallery" to the ul in the index.html file, the workspace didn't update. Make sure to refresh (F5) the browser with the "workspace" preview, even if you have reopened it. Or check the source code if the element imageGallery is really added.
