The instructions say to "select all images in the footer element", but the code shown here is selecting all links in the footer (instead of images).

Also, while the code for task 2 happened to select the correct set of elements, it wasn't coded according to the instructions. The task 2 instructions said, "select all links in the unordered list with the id of gallery"* so it would have been more accurate to use the selector "#gallery a".

And it looks like some lines have been removed from index.html. For this challenge, that file should remain as-is.
