In the case of CSS transitions, element is responsible for applying and unapplying classes. All we have to do is define how the element will look during transition
The syntax is as follows:
<transition name = "nameoftransition"> <div></div> </transition>
Transition elements apply six classes to your markup, you You can use them to handle your entry and exit transitions separately. There are three classes that handle the conversion from A to B when the element is displayed, and three classes that handle the conversion from A to B when the element is removed.
Input transitions occur when a component is enabled or displayed: v-enter, v-enter-active, v-enter-to
v-enter: Indicates entry transition the starting state. Removed at the next frame after the element is inserted
v-enter-active: Indicates the state when the transition is in effect, removed after the animation is completed
v-enter-to:Enter the transition The end state, removed after the animation completes
The leave transition is when the component is disabled or removed: v-leave, v-leave-active, and v-leave-to
v-leave: Indicates the starting state of the leaving transition, and will be removed in the next frame
v-leave-active: Indicates the state when the leaving transition takes effect, throughout the entire leaving transition phase Applied in, removed after transition/animation completes. This class can be used to define the process time, delay and curve function of the leaving transition
v-leave-to: Represents the end state of the leaving transition, removed after the transition/animation is completed

transform: translateX(40px);
opacity:0.2;
