Problem with jquery courses: my workspace has some problem with rgba and position

this is my code: javascript:

//Problem: User when clicking on image goes to a dead end
//Solution: Create an overlay with the large image - Lightbox
var $overlay = $('<div id="overlay"></div>');
var $image = $("<img>");
$("body").append($image);
$("body").append($overlay);


$("#imageGallery a").click(function(event){
  event.preventDefault();

var imagelocation = $(this).attr("href");
  $image.attr("src", imagelocation);

  $overlay.show();

});

and css

#overlay {
 background: rgba(0,0,0,0,7);
  width:100%;
  height:100%;
  position:absolute;
  top:0;
  left:0;
  display:none;
}
#overlay img {margin-top: 30%;}

but the img is not at top left and the screen doesn't become more black as in the course... why?

thx

your rgba is written wrong. It should be like: background: rgba(0,0,0,0.7); Notice the . insted of , at the end there.

Looks like your rgba has an extra element. Please try background: rgba(0,0,0,.7);

Where it should be 0.7 for opacity you've got a comma 0,7
