About Wave Lines
Wave Lines layers sine lines drifting sideways at different speeds, with one accent line in the middle. It reads as data, sound or water, depending on what sits on top.
Wave Lines 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 Wave Lines

- Finance and trading sites.
- Section dividers.
How it works
Lines are SVG paths recomputed from phase each frame. It runs on SVG, 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 Wave Lines
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.
