## zh-CN
会动的进度条才是好进度条。
## en-US
A dynamic progress bar is better.
```jsx
import { Progress, Button } from 'antd';
import { MinusOutlined, PlusOutlined } from '@ant-design/icons';
class App extends React.Component {
state = {
percent: 0,
};
increase = () => {
let percent = this.state.percent + 10;
if (percent > 100) {
percent = 100;
}
this.setState({ percent });
};
decline = () => {
let percent = this.state.percent - 10;
if (percent < 0) {
percent = 0;
}
this.setState({ percent });
};
render() {
return (
<>
} />
} />
>
);
}
}
ReactDOM.render(, mountNode);
```
