.fade-enter-active{ }Enter the end state of the transition, which takes effect when the element is inserted, and is removed after transition/animation is completed. This class can be used to define transition process times, delays and curve functions.

.fade- leave-active{ }Leaves the end state of the transition, takes effect when the element is deleted, and is removed after transition/animation is completed. This class can be used to define transition process times, delays and curve functions.
