## What it is
Lenis is a lightweight, dependency-free smooth scroll library for modern browsers that wraps native scrolling to keep accessibility, sticky positioning, and anchor links working. It syncs DOM and WebGL scroll scenes and ships first-class adapters for React, Vue, and Framer.

## Use cases
- add smooth scrolling to a website
- sync WebGL scenes with page scroll
- build parallax scroll effects
- smooth scroll for React app
- scroll snapping between sections
- consistent scroll feel across wheel trackpad and touch
- drive GSAP ScrollTrigger with smooth scroll

## When to choose
- you want smooth scrolling without hijacking scrollbars or breaking accessibility
- you need scroll-linked WebGL or animation effects perfectly in sync with the DOM
- you want a tiny zero-dependency library with framework adapters
- you need vertical, horizontal, or nested smooth scrolling

## When to avoid
- you prefer fully native browser scrolling with no smoothing
- your site targets very old browsers
- you need scroll hijacking with custom scrollbars or CSS-transform-based scrolling
