Usage

usage.tsx
import { BackgroundBeamsWithCollision } from "@/components/ui/background-beams-with-collision";export function Example() {  return (    <BackgroundBeamsWithCollision>      <div className="relative z-10 px-6 text-center">        <h1 className="text-4xl font-bold">Build something remarkable</h1>        <p className="mt-4">A short introduction for your landing page.</p>      </div>    </BackgroundBeamsWithCollision>  );}
  • Hero sections that need a dramatic animated background without obscuring foreground content.
  • Landing pages, product introductions, and marketing sections with a dark or light theme.
  • Decorative backgrounds for centered headings, descriptions, or calls to action.
  • Visual search terms involving beams, falling light, particle explosions, or collision effects.

Examples

Hero section with a call to action

Uses the component as a full-width hero backdrop while keeping the content above the animated beams.

hero-section-with-a-call-to-action.tsx
import { BackgroundBeamsWithCollision } from "@/components/ui/background-beams-with-collision";export function Hero() {  return (    <BackgroundBeamsWithCollision className="min-h-[32rem]">      <div className="relative z-10 max-w-2xl px-6 text-center">        <h1 className="text-5xl font-bold tracking-tight">Ship your next idea</h1>        <p className="mt-6 text-neutral-600 dark:text-neutral-300">          Turn a concept into a polished product with a focused workflow.        </p>        <button className="mt-8 rounded-md bg-black px-5 py-3 text-white dark:bg-white dark:text-black">          Get started        </button>      </div>    </BackgroundBeamsWithCollision>  );}

Product announcement

Places announcement content over the collision animation with a custom class for a taller presentation.

product-announcement.tsx
import { BackgroundBeamsWithCollision } from "@/components/ui/background-beams-with-collision";export function Announcement() {  return (    <BackgroundBeamsWithCollision className="md:h-[48rem]">      <div className="relative z-10 px-6 text-center">        <span className="rounded-full border px-3 py-1 text-sm">New release</span>        <h2 className="mt-6 text-4xl font-semibold">Automation, now in one place</h2>      </div>    </BackgroundBeamsWithCollision>  );}

Centered sign-up panel

Wraps a compact registration prompt in the animated background while preserving the component's default responsive height.

centered-sign-up-panel.tsx
import { BackgroundBeamsWithCollision } from "@/components/ui/background-beams-with-collision";export function SignUpPanel() {  return (    <BackgroundBeamsWithCollision>      <div className="relative z-10 w-full max-w-md rounded-xl border bg-white/80 p-8 shadow-sm backdrop-blur dark:bg-neutral-900/80">        <h2 className="text-2xl font-semibold">Join the waitlist</h2>        <p className="mt-2 text-sm text-neutral-600 dark:text-neutral-300">          Be the first to know when we launch.        </p>      </div>    </BackgroundBeamsWithCollision>  );}

API reference

PropTypeDefaultDescription
childrenReact.ReactNode—The React content rendered inside the animated container, above the beam and collision layers.
classNamestring | undefined—Optional class name merged with the component's built-in container classes using cn.

Accessibility

  • The component provides decorative animation but does not add semantic structure, labels, or ARIA attributes; supply meaningful headings, text, and controls through children.
  • Keep foreground content readable against both the light and dark gradient backgrounds, and verify sufficient color contrast for custom children.
  • The source does not implement prefers-reduced-motion handling, so consider providing an application-level motion preference strategy if the animation is nonessential.
  • The bottom collision surface is pointer-events-none and does not create an interactive control.
