Installation

pnpm dlx shadcn@latest add @magicui/border-beam

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

Usage

usage.tsx
import { BorderBeam } from "@/components/ui/border-beam"export function Example() {  return (    <div className="relative overflow-hidden rounded-xl border bg-card p-6">      <h3 className="text-lg font-semibold">Featured plan</h3>      <p className="text-muted-foreground">A panel highlighted with an animated border beam.</p>      <BorderBeam />    </div>  )}
  • Highlight cards, panels, dialogs, or feature sections with a subtle animated border.
  • Add visual emphasis to CTAs, featured content, pricing tiers, or newly launched features.
  • Use as a decorative effect around dashboards, product previews, and hero sections.
  • Pair with dark or gradient surfaces when a neon, premium, or futuristic visual treatment is appropriate.

Examples

Featured card

A default orange-to-purple beam around a highlighted card.

featured-card.tsx
import { BorderBeam } from "@/components/ui/border-beam"export function FeaturedCard() {  return (    <div className="relative overflow-hidden rounded-2xl border bg-background p-6">      <h2 className="text-xl font-semibold">Pro plan</h2>      <p className="mt-2 text-sm text-muted-foreground">Everything you need to ship faster.</p>      <BorderBeam />    </div>  )}

Custom cyan beam

A slower, larger beam with custom colors and border width.

custom-cyan-beam.tsx
import { BorderBeam } from "@/components/ui/border-beam"export function ProductPreview() {  return (    <div className="relative overflow-hidden rounded-xl border bg-slate-950 p-8">      <div className="relative z-10 text-white">Live product preview</div>      <BorderBeam        size={80}        duration={10}        colorFrom="#22d3ee"        colorTo="#2563eb"        borderWidth={2}      />    </div>  )}

Reversed beam with delayed start

A beam traveling in the reverse direction with a custom initial offset.

reversed-beam-with-delayed-start.tsx
import { BorderBeam } from "@/components/ui/border-beam"export function AnnouncementPanel() {  return (    <div className="relative overflow-hidden rounded-lg border bg-muted p-5">      <p className="relative z-10 font-medium">New features are now available.</p>      <BorderBeam        reverse        initialOffset={35}        delay={1.5}        duration={7}        colorFrom="#f472b6"        colorTo="#a855f7"      />    </div>  )}

API reference

PropTypeDefaultDescription
sizenumber | undefined50Size of the square beam in pixels and the radius used by its motion path.
durationnumber | undefined6Animation duration in seconds for one traversal.
delaynumber | undefined0Delay value in seconds. The component applies it as a negative Motion transition delay, offsetting the animation's starting phase.
colorFromstring | undefined"#ffaa40"Starting color of the beam gradient.
colorTostring | undefined"#9c40ff"Color used toward the beam gradient's middle.
transitionTransition | undefined—Additional Motion transition options. These are merged after the component defaults and can override them.
classNamestring | undefined—Additional class names applied to the animated beam element.
styleReact.CSSProperties | undefined—Inline styles applied to the animated beam element. These are merged after its generated width, offset path, and color custom properties.
reverseboolean | undefinedfalseReverses the animation direction.
initialOffsetnumber | undefined0Initial offset position along the motion path, expressed as a percentage from 0 to 100.
borderWidthnumber | undefined1Border width in pixels used by the masking container.

Accessibility

  • The beam is decorative: its wrapper uses pointer-events-none and contains no text or interactive controls.
  • Keep meaningful headings, labels, and content in the surrounding container; do not rely on the animation alone to communicate status or importance.
  • The component does not implement reduced-motion handling itself. If motion sensitivity is a concern, conditionally render it or override the animation behavior at the application level.
  • Use a relatively positioned parent so the absolutely positioned beam is contained within the intended panel.
