vue3内置过渡动画

cn.vuejs.org/guide/built…官方文档

为过渡效果命名

<Transition name="fade">
  ...
</Transition>

.fade-enter-active,
.fade-leave-active {
  transition: opacity 0.5s ease;
}

.fade-enter-from,
.fade-leave-to {
  opacity: 0;
}

可以更换name,name的命名必须与css类名前缀一致

<Transition name="abc">
  ...
</Transition>

.abc-enter-active,
.abc-leave-active {
  transition: opacity 0.5s ease;
}

.abc-enter-from,
.abc-leave-to {
  opacity: 0;
}
