### 应用场景 ###

vue项目中，某些时候需要将某些区块的进入进出做成动画的形式，给项目增加交互特色。 vue中可以用transition来包裹区块内容，设定进入进出的时间和动画状态。

### transition 使用实现步骤 ###

1.  把需要添加动画的元素用 transition 标签包起来

<transition name="left">
    	<div class="leftpart" v-show="isLeft">
    		gis-dajianshi
    	</div>
    </transition>

1.  给这个 transition 标签一个名字（比如 left）
2.  添加入场动画， class 类名是 “标签名字 + enter-active”

.left-leave 
    .left-enter-active

1.  定义动画效果（@keyframes）
