Why cant I use $('#modal').append?

In this code challenge, we were supposed to append a dismiss button unto a <div> with the id="modal". This div gets saved as a jQuery Object into a variable called $modal.

obviously, ----- $modal.append($button); ----- works to append the button object unto the modal,

but when I tried selecting the <div> using its #id name like $('#modal').append($button);

So do I have to predefine jQuery objects as variables to use further methods on them?

The reason "$('#modal').append($dismissButton);" would not work is that you are attempting to do it before the modal div has been placed on the document.

:point_right: If you put it after line 16 (when $modal is appended to the document body), it does work.
