# QueueAnim

- category: Components
- chinese: 进出场动画

---

通过简单的配置对一组元素添加串行的进场动画效果。

## 何时使用

- 从内容A到内容B的转变过程时能有效的吸引用户注意力，突出视觉中心，提高整体视觉效果。

- 小的信息元素排布或块状较多的情况下，根据一定的路径层次依次进场，区分维度层级，来凸显量级，使页面转场更加流畅和舒适，提高整体视觉效果和产品的质感。

- 特别适合首页和需要视觉展示效果的宣传页，以及单页应用的切换页面动效。


## API

元素依次进场。

```html
<QueueAnim>
  <div key='demo1'>依次进场</div>
  <div key='demo2'>依次进场</div>
  <div key='demo3'>依次进场</div>
  <div key='demo4'>依次进场</div>
</QueueAnim>
```

> 每个子标签必须带 key，如果未设置 key 将不执行动画。
