Custom scroll with inertia, smooth parallax and scenes manager.
rolly.js is a library written in javascript for building pages that moves smoothly.
This library offers 3 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…)

- Create documentation
- Create some examples
- Fix the scrollTo function
- Test and fix issues when
verticaloptions is set tofalse - 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 🤩)
- Need a feature?
