Disable the document's scrolling.

It's silly how many libraries have their own implementation of this. So I thought I'd make a module that other libraries could use.

Here's how this works:

• When you turn it on(), the documentElement is styled with width: calc(100% - scrollbarSize), position: fixed, top: currentScrollTop, and overflow: hidden.
• When you turn it off(), everything goes back to the way it was before.

npm install no-scroll

Dependencies: none.

Desktop: IE9+

Mobile: Has no effect in iOS, where this simple approach does not work. For a more complex approach that aims to block scrolling on iOS, try body-scroll-lock.

This module exposes three simple functions: on(), off() and toggle().

var noScroll = require('no-scroll');

// To turn off the document's scrolling
noScroll.on();

// To restore scrolling
noScroll.off();

// To toggle scrolling
noScroll.toggle();

If you do not have a CommonJS environment (no module.exports), the module exposes the global object noScroll.
