You cannot change the world, but you can change a scrollbar!

Baron — a small, fast and crossbrowser custom scrollbar with native system scroll mechanic.

Features

• Doesn't replace native system scroll mechanic.
• Customizable scrollbar design with full CSS support.
• Does not depend on external libraries (since v3).
• Can be inited on hidden blocks
• Vertical, horizontal and bidirectional scroll
• Infinite scroll
• Nested scrollers

Baron does not replace the native scrollbar, just hides it. This guarantees scrolling will work in any browser.

1. Hiding system scrollbar

• Include baron.js and some css:

<script src="baron.js"></script>
<style>
    ::-webkit-scrollbar { /* for Mac OS X support */
        width: 0;
    }
</style>

• Initialize baron on your scroller:

baron('.my-scroller');

2. Making your own custom-designed scrollbar

You can do everything you want with CSS of your custom scrollbar. There are some required and recommended css rules (see base css) – do not forget to use them. You can also use predefined skins.

Webpack

Just import baron and use it:

import baron from 'baron';
// or: const baron = require('baron');

baron({ scroller: ... });

Version for development

Note, that baron.js is a development version. It contains additional code and log messages, to make the development process easier.

baron.min.js is a production-ready version: weight less, works a little bit faster.

Nested scrollers

Baron supports nested scrollers. To make scrollers happy, follow the rule:

• Initialize baron instances from ancestor to descendant scrollers order.

Third World War will not begin if you break that rule, but there may be some bad user-experience with baron-instances updates (when size of one scroller depends on size of another). See /demo source.

Browsers support

Baron uses two old CSS 2.1 technologies: 1) overflow: scroll 2) overflow: hidden.

8+ ✔	3.6+ ✔	10+ ✔	11.5+ ✔	5.1+ ✔	4+ ✔

Wanna support ie6 and Opera 9? Try baron@2 version + jQuery. Version 3+ uses classList API and style attribute.

3.0 migration

1. Make sure you are satisfied with new supported browser list.
2. Remove $ and event params if any. You also could remove jQuery from your page.
3. Make sure you have one html node per one initialization: multi-baron not supported.
4. pull plugin removed, so you cannot use it anymore. But you can add it manually.

2.0 migration

impact param default value changed to scroller for all directions. That impact horizontal scrollbars.

If you use % cross-paddings (padding-left and padding-right for vertical direction) for scroller, it will be buggy in Mac OS X Firefox because of need for extra-padding to support it. Use pixels instead, or make html-container inside scroller.

Also, checkout changelog.

1.0 migration

If you have any problems, just set cssGuru option to true.
