CodeSandBoxes of documentation have import error 'ModuleNotFoundError'

[AlexString]

Opening (I think) any CodeSandBox of slider-react-component.vercel.app has this import error

I have only opened Marks and Slider demos

A Slider demo with import error: https://codesandbox.io/s/p8ytog

I changed :

import 'rc-slider/dist/rc-slider.css';

to:

import 'rc-slider/assets/index.css';

So it works well with this importation.

Also it would be nice to find a page where it can be showed how to style these Slidebars, I didn't find any.
