Currently only supports vertical scroll due to cultural norms

While there is somewhat of a support for scrollbar customization through CSS, it is not fully supported in all browsers / older versions and the level of customization isn't flexible enough to allow creativity or certain special product needs.

👉 Make sure to import fakescroll.css

Install (CDN):

npm i @yaireo/fakescroll

React port

import FakeScroll from '@yaireo/fakescroll/react.fakescroll.js'
import '@yaireo/fakescroll/fakescroll.css'

const onFakeScrollChange = ({ scrollRatio }) => console.log(scrollRatio)

<FakeScroll className='foo' track='smooth' onChange={onFakeScrollChange}>
    ...
</FakeScroll>

Example markup:

<div class="foo">
    ...
    ...
    ...
</div>

Initialize custom scrollbar with callback:

var myScrollbar = document.querySelector('.foo').fakeScroll({
    onChange: () => console.log( myScrollbar.scrollRatio )
})

The onChange also has a scrollRatio propery in its argument:

document.querySelector('.foo--outside').fakeScroll({
    onChange: ({ scrollRatio }) => console.log( scrollRatio )
});

The above markup will now become:

<div class="foo fakeScroll fakeScroll--hasBar">
    <div class="fakeScroll__wrap">
        <div class="fakeScroll__content">
            ...
            ...
            ...
        </div>
    </div>
    <div class="fakeScroll__bar"></div>
</div>

Browser support

The script probably won't work on IE without Babel & ES2015 polyfills.
