Installation

pnpm dlx shadcn@latest add @aceternity/background-beams

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

Usage

usage.tsx
import { BackgroundBeams } from "@/components/ui/background-beams";export function HeroBackground() {  return <BackgroundBeams className="opacity-80" />;}
  • As a decorative background behind hero sections, landing-page headers, or marketing content.
  • To add motion and a futuristic visual style to empty or dark layouts.
  • When the surrounding content should remain in normal HTML while the beams sit behind it.
  • For visual emphasis around prominent product introductions or calls to action.

Examples

Hero section background

Place the beams behind hero content with a relatively positioned container.

hero-section-background.tsx
import { BackgroundBeams } from "@/components/ui/background-beams";export function Hero() {  return (    <section className="relative isolate overflow-hidden bg-slate-950 px-6 py-32 text-white">      <BackgroundBeams className="opacity-70" />      <div className="relative z-10 mx-auto max-w-3xl text-center">        <h1 className="text-5xl font-bold tracking-tight">Build the future faster.</h1>        <p className="mt-6 text-slate-300">A focused workspace for ambitious teams.</p>      </div>    </section>  );}

Card decoration

Use a clipped beam layer as a subtle visual treatment inside a feature card.

card-decoration.tsx
import { BackgroundBeams } from "@/components/ui/background-beams";export function FeatureCard() {  return (    <article className="relative isolate overflow-hidden rounded-2xl border bg-background p-8">      <BackgroundBeams className="opacity-30" />      <div className="relative z-10">        <h2 className="text-xl font-semibold">Real-time collaboration</h2>        <p className="mt-2 text-muted-foreground">Work together without losing momentum.</p>      </div>    </article>  );}

Page-level background

Apply a low-opacity beam layer across a page region while keeping content above it.

page-level-background.tsx
import { BackgroundBeams } from "@/components/ui/background-beams";export function AboutPage() {  return (    <main className="relative min-h-screen overflow-hidden bg-black text-white">      <BackgroundBeams className="opacity-40" />      <div className="relative z-10 mx-auto max-w-5xl px-6 py-24">        <h1 className="text-4xl font-bold">About our studio</h1>      </div>    </main>  );}

API reference

classNamestring | undefinedundefinedOptional class name merged onto the root absolutely positioned container using cn.

Accessibility

  • The component renders decorative SVG paths without text or semantic content; keep meaningful headings and content in sibling elements.
  • The SVG uses pointer-events-none, so it does not block interaction with content layered above it.
  • The source does not implement prefers-reduced-motion handling; provide an alternative or disable/hide the component when reduced motion is important.
  • Ensure foreground text and controls maintain sufficient contrast against the animated background.
