## Carousel 组件示例
### 基本
最简单的用法。

```tsx
import React from 'react';
import { Carousel } from 'antd';
const contentStyle: React.CSSProperties = {
  margin: 0,
  height: '160px',
  color: '#fff',
  lineHeight: '160px',
  textAlign: 'center',
  background: '#364d79',
};
const App: React.FC = () => {
  const onChange = (currentSlide: number) => {
    console.log(currentSlide);
  };
  return (
    <Carousel afterChange={onChange}>
      <div>
        <h3 style={contentStyle}>1</h3>
      </div>
      <div>
        <h3 style={contentStyle}>2</h3>
      </div>
      <div>
        <h3 style={contentStyle}>3</h3>
      </div>
      <div>
        <h3 style={contentStyle}>4</h3>
      </div>
    </Carousel>
  );
};
export default App;
```
### 位置
位置有 4 个方向。

```tsx
import React, { useState } from 'react';
import type { CarouselProps, RadioChangeEvent } from 'antd';
import { Carousel, Radio } from 'antd';
type DotPlacement = CarouselProps['dotPlacement'];
const contentStyle: React.CSSProperties = {
  margin: 0,
  height: '160px',
  color: '#fff',
  lineHeight: '160px',
  textAlign: 'center',
  background: '#364d79',
};
const App: React.FC = () => {
  const [dotPlacement, setDotPlacement] = useState<DotPlacement>('top');
  const handlePositionChange = ({ target: { value } }: RadioChangeEvent) => {
    setDotPlacement(value);
  };
  return (
    <>
      <Radio.Group onChange={handlePositionChange} value={dotPlacement} style={{ marginBottom: 8 }}>
        <Radio.Button value="top">Top</Radio.Button>
        <Radio.Button value="bottom">Bottom</Radio.Button>
        <Radio.Button value="start">Start</Radio.Button>
        <Radio.Button value="end">End</Radio.Button>
      </Radio.Group>
      <Carousel dotPlacement={dotPlacement}>
        <div>
          <h3 style={contentStyle}>1</h3>
        </div>
        <div>
          <h3 style={contentStyle}>2</h3>
        </div>
        <div>
          <h3 style={contentStyle}>3</h3>
        </div>
        <div>
          <h3 style={contentStyle}>4</h3>
        </div>
      </Carousel>
    </>
  );
};
export default App;
```
### 自动切换
定时切换下一张。

```tsx
import React from 'react';
import { Carousel } from 'antd';
const contentStyle: React.CSSProperties = {
  margin: 0,
  height: '160px',
  color: '#fff',
  lineHeight: '160px',
  textAlign: 'center',
  background: '#364d79',
};
const App: React.FC = () => (
  <Carousel autoplay>
    <div>
      <h3 style={contentStyle}>1</h3>
    </div>
    <div>
      <h3 style={contentStyle}>2</h3>
    </div>
    <div>
      <h3 style={contentStyle}>3</h3>
    </div>
    <div>
      <h3 style={contentStyle}>4</h3>
    </div>
  </Carousel>
);
export default App;
```
### 渐显
切换效果为渐显。

```tsx
import React from 'react';
import { Carousel } from 'antd';
const contentStyle: React.CSSProperties = {
  margin: 0,
  height: '160px',
  color: '#fff',
  lineHeight: '160px',
  textAlign: 'center',
  background: '#364d79',
};
const App: React.FC = () => (
  <Carousel effect="fade">
    <div>
      <h3 style={contentStyle}>1</h3>
    </div>
    <div>
      <h3 style={contentStyle}>2</h3>
    </div>
    <div>
      <h3 style={contentStyle}>3</h3>
    </div>
    <div>
      <h3 style={contentStyle}>4</h3>
    </div>
  </Carousel>
);
export default App;
```
### 切换箭头
显示切换箭头。

```tsx
import React from 'react';
import { Carousel } from 'antd';
const contentStyle: React.CSSProperties = {
  margin: 0,
  height: '160px',
  color: '#fff',
  lineHeight: '160px',
  textAlign: 'center',
  background: '#364d79',
};
const App: React.FC = () => (
  <>
    <Carousel arrows infinite={false}>
      <div>
        <h3 style={contentStyle}>1</h3>
      </div>
      <div>
        <h3 style={contentStyle}>2</h3>
      </div>
      <div>

      <div>
        <h3 style={contentStyle}>1</h3>
      </div>
      <div>
        <h3 style={contentStyle}>2</h3>

  height: '160px',
  color: '#fff',
  lineHeight: '160px',

### 组件 Token
Component Token Debug.

```tsx
import React from 'react';
import { Carousel, ConfigProvider } from 'antd';
/** Test usage. Do not use in your production. */
const contentStyle: React.CSSProperties = {
  margin: 0,
  height: '160px',
  color: '#fff',
  lineHeight: '160px',
  textAlign: 'center',
  background: '#364d79',
};
export default () => (
  <ConfigProvider
    theme={{
      components: {
        Carousel: {
          dotWidth: 50,
          dotHeight: 50,
          dotActiveWidth: 80,
        },
      },
    }}
  >
    <Carousel>
      <div>
        <h3 style={contentStyle}>1</h3>
      </div>
      <div>
        <h3 style={contentStyle}>2</h3>
