Idea:

(1) Think about how the numbers in each entry are updated.

(2) Animation effect of shopping cart.

(3) How to display the shopping list (I haven't written this yet. If necessary, you can leave me a message under my simple book).

I didn't write the pop-up list function of the shopping cart. If necessary, you can leave a message in my simple book
