About Flow Field
Flow Field sends hundreds of particles along a slowly shifting current, leaving silky trails. It is generative art behind a heading.
Flow Field 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 Flow Field
- Creative studio heroes.
- AI and generative products.
- Music and art releases.
- About and mission pages.
How it works
Particles move along angles from a noise field that drifts over time, drawn with fading trails. It runs on a canvas capped at 2x pixel density, pauses when scrolled off screen, and reads its colours from your theme tokens so it follows dark mode.
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 Flow Field
Every prop is documented in the API reference above with its type and default. The ones you will reach for first are listed here.
Style it with className like any other element. It only uses your theme's tokens, so it follows light and dark mode without extra work.
- particles (number, default 900).
- fade (number, default 0.06): Lower means longer trails.
