`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`.
