CSS 动画
CSS 动画用法同 CSS 过渡，区别是在动画中
v-enter类名在节点插入 DOM 后不会立即删除，而是在animationend事件触发时删除。
示例：(省略了兼容性前缀)
<div id="example-2">
<button @click="show = !show">Toggle show</button>
<transition name="bounce">
<p v-if="show">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Mauris facilisis enim libero, at lacinia diam fermentum id. Pellentesque habitant morbi tristique senectus et netus.</p>
</transition>
</div>
new Vue({
el: '#example-2',
data: {
show: true
}
})
.bounce-enter-active {
animation: bounce-in .5s;
}
.bounce-leave-active {
animation: bounce-in .5s reverse;
}
@keyframes bounce-in {
0% {
transform: scale(0);
}
50% {
transform: scale(1.5);
}
100% {
transform: scale(1);
}
}
