rolly.js

Custom scroll with inertia, smooth parallax and scenes manager.

What is rolly.js?

rolly is a library written in javascript for building pages that moves smoothly.

This library was created with the aim of offering three main features:

change the behavior of the default scroll for a smoother effect
quickly and flexibly add a customizable parallax effect to any element on a page
add any behavior to your scenes bound to the scroll state (custom transforms, seek animations…)

Roadmap

[x] Create documentation
[x] Create some examples
[ ] Fix the scrollTo function
[ ] Test and fix issues when vertical options is set to false
[ ] Change the way the easing is computed. Probably with a clean Lerp function
[ ] Implement different easing for each scene (it would add a nice organic effect 🤩)
