I meant that the code is made from

4 parts right ?

1. Body
2. summary-inner
3. Yith-wcwl-add-to-wishlist
4. a

And then is the case styling

Body is like the main body, summary-inner is a div in the html. yith-wcwl-add-to-wishlist is a div too?

And the “a” is because the class is
a.yith-wcwl-add-to-wishlist?

body .summary-inner>.yith-wcwl-add-to-wishlist a {
display:none;
}
