scroll-reveal

scroll-reveal

A gentle rise + fade as elements scroll into view. Part of motion-anything; obeys MOTION-SPEC.md.

When to use it

• Long landing pages and stacked content sections.
• Giving a page a calm sense of pace.

When NOT to use it (restraint)

• Above-the-fold hero content the reader must see instantly.
• Revealing many elements simultaneously — stagger them, max ~3 at once.

How to apply

1. Copy scroll-reveal.css and scroll-reveal.js into the project, and link them.
2. Mark elements:

   <section data-reveal>…</section>
   <li data-reveal data-reveal-delay="80">…</li>   <!-- optional stagger, ms -->
   

3. An IntersectionObserver adds .is-in once, when the element enters the viewport.

Accessibility & performance

• prefers-reduced-motion: everything is shown immediately, no travel.
• Animates transform/opacity only; unobserves each element after it reveals.

Framework notes

• React: render data-reveal attributes and run the init (or an equivalent useEffect + IntersectionObserver) after mount.
