Hey! Thanks!
Final goal is to manipulate with several parameters together (background-color, dropshadow, scale) and one at a time. To highlight only one block lose the highlight after another one gets it.
But I'll try to figure something out.
I'm wondering if there's a way looping trough child elements of pinned section. See Codepen. List items should get .active class added and then removed one-by-one.
