About Dot Field

Dot Field is a field of dots whose size breathes with a travelling noise wave, and that parts around the pointer.

Dot 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 Dot Field

  • Subtle hero backgrounds.
  • Developer and docs sites.
  • Behind stats and features.
  • Empty states.

How it works

Dot size comes from a moving noise wave and pointer distance. 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 Dot 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.

The Customize panel next to the preview lets you change gap, size, speed, color live, and the Code tab updates to match, so the snippet you copy already carries your values.

  • gap (number, default 20): Pixels between dots.
  • size (number, default 3): Largest dot radius in px.
  • speed (number, default 1).
  • color (string, default "var(--muted-foreground)").
  • radius (number, default 120): Pointer influence radius in px.

Goes well with Dot Field

These backgrounds pieces share its tokens and motion language, so they sit together on one page without clashing.

  • Smoke: A slow React smoke background: blurred plumes drifting over dark sections, CSS only
  • Aurora: An animated React aurora background: soft light bands drifting across a section
  • Grid Beams: A React grid background with beams of light running along its lines
