先简单介绍下 transition 标签的使用方法
主要用于 v-show, v-if 或 router-view 的进出场动画
<transition name="name" >
<div v-show="show" ></div>
<div v-if="show" ></div>
<router-view/>
</transition>
// 定义进入前与离开后状态
.name-enter, .name-leave-to {
...
}
// 定义离开前与进入后状态
.name-leave, .name-enter-to {
...
}
// 定义进出过程
.name-enter-active, .name-leave-active {
transition: all .5s
}

.fade-enter, .fade-leave-to {

.fade-leave, .fade-enter-to {
