Usage

usage.tsx
import { AuroraBackground } from "@/components/ui/aurora-background";export default function Example() {  return (    <AuroraBackground>      <section className="relative z-10 px-6 text-center">        <h1 className="text-4xl font-bold">Build something remarkable</h1>        <p className="mt-4">A calm animated backdrop for your next launch.</p>      </section>    </AuroraBackground>  );}
  • Hero sections with prominent foreground content or calls to action.
  • Landing-page headers, marketing pages, and promotional layouts.
  • Full-viewport empty states or visually expressive authentication screens.
  • Background treatments where the animated effect should remain behind interactive content.

Examples

Hero with a call to action

Use the default radial mask to frame centered marketing content.

hero-with-a-call-to-action.tsx
import { AuroraBackground } from "@/components/ui/aurora-background";export default function Hero() {  return (    <AuroraBackground>      <div className="relative z-10 max-w-2xl px-6 text-center">        <p className="text-sm font-medium uppercase tracking-widest">Acme Studio</p>        <h1 className="mt-4 text-5xl font-semibold tracking-tight">Design without limits</h1>        <button className="mt-8 rounded-full bg-slate-950 px-5 py-3 text-white dark:bg-white dark:text-slate-950">Get started</button>      </div>    </AuroraBackground>  );}

Background without radial masking

Disable the radial mask when the animated gradient should cover the entire background evenly.

background-without-radial-masking.tsx
import { AuroraBackground } from "@/components/ui/aurora-background";export default function FullGradientPanel() {  return (    <AuroraBackground showRadialGradient={false} className="min-h-screen">      <div className="relative z-10 grid gap-4 px-6 text-center">        <h2 className="text-3xl font-bold">Explore the collection</h2>        <p>Browse the latest releases from our team.</p>      </div>    </AuroraBackground>  );}

Interactive content with HTML div props

Pass standard div attributes such as an id, data attribute, and event handler to the component's background container.

interactive-content-with-html-div-props.tsx
import { AuroraBackground } from "@/components/ui/aurora-background";export default function InteractiveAurora() {  return (    <AuroraBackground id="welcome" data-testid="welcome-background" onClick={() => console.log("background clicked")}>      <div className="relative z-10 rounded-xl border border-white/30 p-8 text-center backdrop-blur-sm">        <h1 className="text-2xl font-semibold">Welcome back</h1>      </div>    </AuroraBackground>  );}

API reference

PropTypeDefaultDescription
childrenReactNode—Required content rendered above the animated background.
showRadialGradientbooleantrueControls the radial mask applied to the animated gradient. Set to false to remove the mask.
classNamestring—Optional classes merged with the component's root background container classes.
...propsReact.HTMLProps<HTMLDivElement>—All other standard HTML div props are spread onto the root background container, including attributes, event handlers, and style-related props.

Accessibility

  • The component does not add ARIA labels, roles, or announcements for the animation; treat the aurora as decorative and provide accessible text through children.
  • Keep foreground content readable against the animated background and preserve visible keyboard focus styles for interactive children.
  • The component renders a main element, so use it only where an additional page-level main landmark is appropriate.
  • The animation is CSS-driven and the component does not include a reduced-motion preference override; add one in application CSS if motion reduction is required.
