BackTop

BackTop makes it easy to go back to the top of the page.

When To Use#

  • When the page content is very long.

  • When you need to go back to the top very frequently in order to view the contents.

Examples

Scroll down to see the bottom-right gray button.

The most basic usage.

expand codeexpand code
import { BackTop } from 'antd';

ReactDOM.render(
  <>
    <BackTop />
    Scroll down to see the bottom-right
    <strong className="site-back-top-basic"> gray </strong>
    button.
  </>,
  mountNode,
);
.site-back-top-basic {
  color: rgba(64, 64, 64, 0.6);
}

You can customize the style of the button, just note the size limit: no more than 40px * 40px.

import { BackTop } from 'antd';

const style = {
  height: 40,
  width: 40,
  lineHeight: '40px',
  borderRadius: 4,
  backgroundColor: '#1088e9',
  color: '#fff',
  textAlign: 'center',
  fontSize: 14,
};

ReactDOM.render(
  <div style={{ height: '600vh', padding: 8 }}>
    <div>Scroll to bottom</div>

    <div>Scroll to bottom</div>
    <BackTop>
      <div style={style}>UP</div>
    </BackTop>
  </div>,
  mountNode,
);
