A night highway of glowing light trails on a winding road; press and hold to warp into hyperspace.

Background Studio: tune it below, then copy the code
Your system asks for reduced motion: the demo shows its final state and nothing moves.

Light road example
Code
It follows the controls above: change an option and the code changes with it.
<link rel="stylesheet" href="/axi0/motion/motion.css?v=6">
<script src="/axi0/motion/motion.js?v=10" defer></script>
<axi0-light-road cover></axi0-light-road>import { LightRoad } from "./motion/react/LightRoad";
<LightRoad /><script setup lang="ts">
import LightRoad from "./motion/vue/LightRoad.vue";
</script>
<template>
<LightRoad />
</template>const fx = document.createElement("axi0-light-road");
document.querySelector("#hero").append(fx);The wrappers: LightRoad.tsx (React, TypeScript) and LightRoad.vue (Vue). Both render the same attributes as the HTML; the loader does the rest.
Options
| Attribute | Default | What it does |
|---|---|---|
lanes | 3 | Lanes each way |
curve | 2.2 | How much the road winds |
traffic | 0.85 | How busy the road is |
colors | auto | Colors, comma separated (empty: the palette for the page's theme) |
background | auto | Background color (empty: the theme's) |
speed | 1 | How fast it moves |
theme | auto | Light or dark palette (auto: from the page behind it) |
cover | false | Fill the nearest positioned parent, behind its content |
Accessibility
Decorative: the canvas is aria-hidden and takes no focus; with cover it ignores the pointer, so the content above it stays clickable and readable. The pointer only adds to the motion; touch and keyboard users see the same scene. Drawn by the shared WebGL runner below device resolution (never more than one pixel per CSS pixel, device pixel ratio capped at 2); it starts when it comes within 300 px of the screen, the frame loop stops off screen and in hidden tabs, and reduced motion draws one still frame with no movement. Without WebGL it shows a still gradient in its own colors.
Size
light-road.js is 1.2 KB gzip, with gl.js 2.1 KB and backgrounds-kit.js 3.4 KB it needs. A page loads the loader (2.7 KB) and core.js (1.4 KB) once, whatever it uses.
