Issue 3 : Close the modal when the close button is clicked and when clicking the modal background.

What you need to do

Currently, our modal does not close when the close button is clicked or when the modal background is clicked. Implement this functionality so that users can easily close the modal when they're done viewing the images.

Expected behavior

When a user clicks the close button or the modal background, the modal should close and return to the gallery view:
