:point_right: Something is missing from the provided code.

Take a look at how the placeholder element is created, and then appended to the modal element.

Now look down a couple of lines to see what is being done with the dismissbutton. Based on the example of how the placeholder was handled, can you see what might be needed to get the button to appear on the modal?

Add what's missing to complete the challenge.
