How it works

A sticky element inside a tall section reads scroll progress with useScroll. from, to, tracking, weight and height are props.

The real text stays in the page for screen readers and search engines; the animated letters are decorative copies marked aria-hidden. With prefers-reduced-motion on, it holds still or settles instantly instead of animating.
