Motion On Scroll (MOS)

Effortless, AOS-compatible scroll animations powered by Motion.

Framework-agnostic, MOS lets you add scroll-triggered animations with nothing but data-mos attributes. Under the hood it uses Motion’s powerful animate API, giving you:

• 27 preset effects out of the box
• Support for custom keyframes, easings, and fully bespoke timelines
• AOS-compatible features for painless migration
• First-class TypeScript types
