## zh-CN
|
|
|
|
可以自定义回到顶部按钮的样式，限制宽高：`40px * 40px`。
|
|
|
|
> 注意：`BackTop` 需要一个可接受 `onClick` 事件的元素作为 `children`。 如果您直接将文本作为子项放置，则该组件将无法正常运行。

## en-US

|
You can customize the style of the button, just note the size limit: no more than `40px * 40px`.
|
|
|
|
> Note: `BackTop` expects a element could accept `onClick` propety as children. If you put a text directly as children the component will not function properly.
|
|
|
|
```tsx
|
|
import { BackTop } from 'antd';
|
|
import React from 'react';
|
|
|
|
const style: React.CSSProperties = {
|
|
height: 40,
|
|
width: 40,
|
|
lineHeight: '40px',
|
|
borderRadius: 4,
|
|
backgroundColor: '#1088e9',
|
|
color: '#fff',
|
|
textAlign: 'center',
|
|
fontSize: 14,
|
|
};
|
|
|
|
const App: React.FC = () => (
|
|
<div style={{ height: '600vh', padding: 8 }}>
|
|
<div>Scroll to bottom</div>
