Components Other 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.

API

The distance to the bottom is set to 50px by default, which is overridable.

If you decide to use custom styles, please note the size limit: no more than 40px * 40px.
