// Notes on the classes:
//
// 1. The .carousel-item-left and .carousel-item-right is used to indicate where
//    the active slide is heading.
// 2. .active.carousel-item is the current slide.
// 3. .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.
// 4. .carousel-item-next.carousel-item-left and .carousel-item-prev.carousel-item-right
//    is the upcoming slide in transition.
