Vue组件------入离场动画
入离厂动画
1. 包裹任意元素
html
<transition name="fade">
<element></element>
</transition>2. 添加css样式
css
.fade-enter-active {
transition: all .5s;
}
.fade-enter-active,
.fade-leave-active {
opacity: 1;
background-color: rgba(7, 17, 27, 0.8);
}
.fade-enter,
.fade-leave-to {
opacity: 0;
background-color: rgba(7, 17, 27, 0);
}3.三方插件法
