Shape lattice

A drifting grid of squares, circles, triangles or hexagons lights up under the pointer and leaves a fading rainbow trail that drifts with it.

Background Studio: tune it below, then copy the code

Your system asks for reduced motion: the demo shows its final state and nothing moves.

Shape lattice example

Code

It follows the controls above: change an option and the code changes with it.

<script src="https://search.axi0.io/axi0/motion/motion.js" defer></script>

<axi0-shape-lattice cover></axi0-shape-lattice>

import { ShapeLattice } from "./motion/react/ShapeLattice";

<ShapeLattice />

<script setup lang="ts">
import ShapeLattice from "./motion/vue/ShapeLattice.vue";
</script>

<template>
  <ShapeLattice />
</template>

const fx = document.createElement("axi0-shape-lattice");
document.querySelector("#hero").append(fx);

The wrappers: ShapeLattice.tsx (React, TypeScript) and ShapeLattice.vue (Vue). Both render the same attributes as the HTML; the loader does the rest.

Options

Attribute	Default	What it does
`shape`	`square`	The grid's shape
`size`	`44`	Cell size
`angle`	`45`	Drift direction
`drift`	`18`	Drift speed
`trail`	`1.2`	How long a lit cell takes to fade
`rainbow`	`true`	Color the trail through the rainbow (off: the first palette color)
`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

Decorative: the canvas is aria-hidden and takes no focus; with cover it ignores the pointer, so the content above it stays clickable. With no pointer it lights a wandering path on its own, so touch and keyboard users see the same scene. Drawn on a 2D canvas at device resolution (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.

Size

shape-lattice.js is 1.2 KB gzip, with backgrounds-kit.js 3.4 KB it needs. A page loads the loader (2.9 KB) and core.js (1.4 KB) once, whatever it uses.
