/*
Notes on the classes:
1. .carousel.pointer-event should ideally be pan-y (to allow for users to scroll vertically) even when their scroll action started on a carousel, but for compatibility (with Firefox) we're preventing all actions instead
2. The .carousel-item-left and .carousel-item-right is used to indicate where the active slide is heading.
3. .active.carousel-item is the current slide.
4. .active.carousel-item-left and .active.carousel-item-right is the current slide in its in-transition state. Only one of these occurs at a time.
5. .carousel-item-next.carousel-item-left and .carousel-item-prev.carousel-item-right is the upcoming slide in transition.*/
