About Pattern Waves

Pattern Waves lifts and brightens a repeating pattern of dots, dashes or crosses with a wave travelling across it. Dashes lean with the slope, like reeds.

Pattern Waves 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 Pattern Waves

  • Textured hero backgrounds.
  • Developer and data brands.
  • Section backgrounds.
  • Poster-style pages.

How it works

Each cell's offset and brightness come from the wave at its position. 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 Pattern Waves

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 pattern, cell, amplitude, speed, color live, and the Code tab updates to match, so the snippet you copy already carries your values.

  • pattern ("dots" | "dashes" | "crosses", default "dots").
  • cell (number, default 24): Grid cell size in px.
  • amplitude (number, default 14): Vertical displacement of the wave, in px.
  • speed (number, default 1).
  • color (string, default "var(--ember)"): Any CSS colour, including var(--token).

Goes well with Pattern Waves

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