Floating 3D Particles Demo

A client-side hero example that places a theme-aware floating 3D particle field behind centered heading, supporting text, and a call-to-action button. The particle color switches between white in dark mode and black in light mode.

Installation

pnpm dlx shadcn@latest add @magicui/floating-3d-particles-demo

Requires @magicui in the registries of your components.json (shadcn adds official directory namespaces automatically).

Usage

usage.tsx
import { Floating3DParticles } from "@/registry/magicui/floating-3d-particles"export default function Example() {  return (    <div className="relative flex h-[500px] w-full items-center justify-center overflow-hidden rounded-lg border bg-background">      <Floating3DParticles color="#000000" />      <div className="relative z-10 text-center">        <h2 className="text-3xl font-bold">Build something magical</h2>      </div>    </div>  )}
  • Hero sections that need a subtle animated background without obscuring the primary message.
  • Landing pages introducing a product, portfolio, or creative experience.
  • Call-to-action sections where atmospheric motion should remain behind readable content.
  • Dark- and light-theme interfaces requiring automatic particle contrast.

Examples

Light-theme hero

Uses black particles over a light background with a centered product introduction.

light-theme-hero.tsx
import { Floating3DParticles } from "@/registry/magicui/floating-3d-particles"export default function LightHero() {  return (    <section className="relative flex min-h-[500px] items-center justify-center overflow-hidden bg-background px-6 text-center">      <Floating3DParticles color="#000000" />      <div className="relative z-10 max-w-2xl">        <h1 className="text-4xl font-bold tracking-tight md:text-6xl">Create without limits</h1>        <p className="mt-4 text-muted-foreground">Bring your next idea to life with a focused creative workspace.</p>      </div>    </section>  )}

Dark-theme hero

Uses white particles to maintain contrast in a dark hero section.

dark-theme-hero.tsx
import { Floating3DParticles } from "@/registry/magicui/floating-3d-particles"export default function DarkHero() {  return (    <section className="relative flex min-h-[500px] items-center justify-center overflow-hidden bg-black px-6 text-center text-white">      <Floating3DParticles color="#ffffff" />      <div className="relative z-10 max-w-xl">        <h1 className="text-4xl font-bold md:text-6xl">The future is in motion</h1>        <p className="mt-4 text-white/70">Build immersive experiences with a little extra atmosphere.</p>      </div>    </section>  )}

CTA panel

Combines the particle background with a compact call-to-action panel.

cta-panel.tsx
import { ArrowRight } from "lucide-react"import { Floating3DParticles } from "@/registry/magicui/floating-3d-particles"export default function CtaPanel() {  return (    <div className="relative overflow-hidden rounded-xl border bg-background p-10 text-center">      <Floating3DParticles color="#000000" />      <div className="relative z-10">        <h2 className="text-2xl font-semibold">Ready to get started?</h2>        <button type="button" className="mt-6 inline-flex items-center gap-2 rounded-lg bg-foreground px-5 py-3 text-background">          Start building          <ArrowRight className="size-4" />        </button>      </div>    </div>  )}

Accessibility

  • The demo’s decorative particle field should remain behind content and must not be the sole carrier of meaning.
  • The foreground content uses semantic heading, paragraph, and button elements in the provided example.
  • The CTA is a native button with an explicit type="button" and includes text alongside its icon.
  • Maintain sufficient text contrast against the animated background; the theme-aware black/white particle color helps preserve visual separation.
  • Test motion-sensitive interfaces with reduced-motion preferences if the underlying particle component exposes motion controls in its implementation.
