Can't get the screen to turn black.

I've tried this over and over and I'm not sure what I'm doing wrong. I've tried three different browsers, Safari, Chrome and FireFox. I've also cleared the cache on all three. Still nothing. If anyone could take a look at the code I'd really appreciate it. Thanks in advance.

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

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

I changed widows:100%; to width:100%; and it worked for me.

When you are selecting overlay you are calling the variable containing the div. Instead call the div's id

instead of this:

  $overlay.show();

try this: 

  $("#overlay").show() ;

to phrase it differently, $overlay is for adding things to the html, while using $("#overlay") lets you manipulate the overlay

hmmm, your code works for me. Haveyou tried checking the console with the page open to make sure the the overlay is in the html?

Also I just noticed your CSS rule "widows" may be misspelled

Hi Franklin, Nope that still didn't work. I've been trying different things and have been stuck on this for almost a month now.

Hi Andrew, That was the fix! The CSS for this lesson has "widows" instead of "width" written. Thank you so much!
