SimpleScrollbar

Very simple vanilla javascript library for creating a custom scrollbar cross-browser and cross-devices.

Demo

http://buzinas.github.io/simple-scrollbar

Benefits

Extremely lightweight (less than 1KB after gzip and minify)
It uses the native scroll events, so:
- All the events work and are smooth (mouse wheel, space, page down, page up, arrows etc).
- The performance is awesome!
No dependencies, completely vanilla Javascript!
RTL support (thanks to @BabkinAleksandr)

Browser Support

It was developed for evergreen browsers, but it works both on IE10 and IE11 either.

If you want to make it works down to IE9, the only thing you need to do is to add the classList polyfill.

<!--[if IE 9]><script src="classList.min.js"></script><![endif]-->

Usage

You can use this library as a script tag, or you can import it as a npm module, eg:

CommonJS

const SimpleScrollbar = require('simple-scrollbar');

ES2015 modules

import SimpleScrollbar from 'simple-scrollbar'

Auto-binding

Include the attribute ss-container in any <div> that you want to make scrollable, and the library will turn it for you

<div ss-container>One</div>
<div ss-container>
  <span>Two</span>
</div>

Manual binding

If you want to manually turn your div in a SimpleScrollbar, you can use the SimpleScrollbar.initEl method.

<div class="myClass"></div>
 
<script>
  var el = document.querySelector('.myClass');
  SimpleScrollbar.initEl(el);
</script>

Dynamically added content

If you use some client Framework, like Angular, Aurelia, etc - or any library that includes DOMElements dynamically in your app, and you want to use the SimpleScrollbar ss-container attribute, you can use the SimpleScrollbar.initAll method, and it will turn all the elements with that attribute in a scrollable one for you.

var div = document.createElement('div');
div.insertAdjacentHTML('afterbegin', '<span>One</span>');
div.setAttribute('ss-container', true);
 
var otherDiv = div.cloneNode(true);
otherDiv.querySelector('span').textContent = 'Two';
 
document.body.appendChild(div);
document.body.appendChild(otherDiv);
 
SimpleScrollbar.initAll();
