About Micro Slats
Micro Slats tilts thin vertical slats in a travelling wave like blinds in a breeze, with a tinted layer showing through as they open.
Micro Slats is an animated background for React 19, styled with Tailwind CSS 4 and animated with Motion. It drops into Next.js, Vite, Remix or Astro through the shadcn CLI as a single file you own.
When to use Micro Slats
- Architecture and interior brands.
- Calm hero sections.
- Hospitality and hotels.
- Section dividers.
How it works
Each slat has a staggered rotateY keyframe. It is pure CSS, so it costs almost nothing to keep running, and it stops under reduced motion.
The whole layer is decorative and aria-hidden, sits behind your content without taking pointer events it does not need, and pauses when scrolled off screen. With prefers-reduced-motion on, it holds still or settles instantly instead of animating.
Customizing Micro Slats
Every prop is documented in the API reference above with its type and default. The ones you will reach for first are listed here.
The Customize panel next to the preview lets you change slats, speed, angle live, and the Code tab updates to match, so the snippet you copy already carries your values.
- slats (number, default 48).
- speed (number, default 6): Seconds for one wave to cross.
- angle (number, default 70): Maximum tilt in degrees.
- color (string, default "var(--ember)").
