swinch

The best and most flexible alternative to full-page scroll-controlling javascript plugins

There are no runtime dependencies!!!

The build is dependent on the fantastic zenscroll plugin!

Installation

1. npm install swinch, bower install swinch, yarn add swinch
2. Include dist/swinch.js or swinch.min.js (uses UMD)

Setup

1. After the DOM loads, call swinch.init([sections][, options])
2. When you're done with it, you can call swinch.destroy()

If no sections are set, then document.querySelectorAll('section') will be used by default.
