Thank you very much for answer and another demo, but I have a problem in my previous question that element which is blocking pointer events is wrapper because it is as top layer, in case when I would put wrapper as bottom layer I can`t scrool wrapper where I have eventListener set. I am wondering how I can manage pointer events on steps in case when I need to use wrapper on top. or how I can make animation scrolling with steps with different sizes wihout wrapper.
