Background Studio: tune it below, then copy the code

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

Lift field 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-lift-field cover></axi0-lift-field>

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

<LiftField />

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

<template>
  <LiftField />
</template>

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

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

Options

Attribute	Default	What it does
`count`	`1`	Particle density
`ring`	`1`	Ring size
`spin`	`1`	How fast the ring orbits
`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 and readable. The pointer only adds to the motion; touch and keyboard users see the same scene. Drawn on a 2D canvas (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 the resting state once, with no movement.

Size

lift-field.js is 1.1 KB gzip, with 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.
