Flickering Grid

FlickeringGrid is a client-side animated canvas background that renders a customizable grid of flickering squares. It automatically sizes itself to its container unless explicit dimensions are provided and pauses animation when outside the viewport.

Installation

pnpm dlx shadcn@latest add @magicui/flickering-grid

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

Usage

usage.tsx
import { FlickeringGrid } from "@/components/ui/flickering-grid"export function Example() {  return <FlickeringGrid className="absolute inset-0" />}
  • Add an ambient animated background to hero sections, landing pages, or feature banners.
  • Use behind text, calls to action, or dashboard panels when a subtle technical texture is desired.
  • Use as a lightweight alternative to image-based or SVG background patterns.
  • Avoid using it as the only way to communicate information because the visual animation is decorative and has no semantic content.

Examples

Hero background

Position the grid behind hero content and customize its color, density, and opacity.

hero-background.tsx
import { FlickeringGrid } from "@/components/ui/flickering-grid"export function Hero() {  return (    <section className="relative overflow-hidden rounded-xl px-6 py-24">      <FlickeringGrid        className="absolute inset-0 -z-10"        color="rgb(59, 130, 246)"        squareSize={3}        gridGap={8}        maxOpacity={0.2}        flickerChance={0.15}      />      <div className="relative">        <h1 className="text-4xl font-bold">Build faster with your team</h1>        <p className="mt-4 max-w-xl text-muted-foreground">A subtle animated background for product-focused landing pages.</p>      </div>    </section>  )}

Fixed-size card decoration

Use explicit width and height when the grid should occupy a predictable canvas size inside a card.

fixed-size-card-decoration.tsx
import { FlickeringGrid } from "@/components/ui/flickering-grid"export function StatsCard() {  return (    <div className="relative overflow-hidden rounded-lg border p-6">      <FlickeringGrid        className="absolute inset-0"        width={360}        height={180}        color="rgb(16, 185, 129)"        squareSize={4}        gridGap={10}        maxOpacity={0.16}      />      <div className="relative">        <p className="text-sm text-muted-foreground">Active users</p>        <p className="mt-2 text-3xl font-semibold">24,892</p>      </div>    </div>  )}

Dense dark-mode texture

Create a denser, low-opacity grid for a dark panel or command-style interface.

dense-dark-mode-texture.tsx
import { FlickeringGrid } from "@/components/ui/flickering-grid"export function DarkPanel() {  return (    <div className="relative min-h-64 overflow-hidden rounded-xl bg-slate-950 p-8 text-white">      <FlickeringGrid        className="absolute inset-0"        color="rgb(148, 163, 184)"        squareSize={2}        gridGap={5}        flickerChance={0.08}        maxOpacity={0.12}      />      <div className="relative">        <p className="font-mono text-sm text-slate-300">SYSTEM STATUS</p>        <p className="mt-3 text-2xl font-semibold">All systems operational</p>      </div>    </div>  )}

API reference

PropTypeDefaultDescription
squareSizenumber | undefined4Size of each grid square in CSS pixels.
gridGapnumber | undefined6Gap between grid squares in CSS pixels.
flickerChancenumber | undefined0.3Per-second probability factor used to replace each square's opacity during animation updates.
colorstring | undefined"rgb(0, 0, 0)"CSS color string converted to RGB and used for the square fill color.
widthnumber | undefinedundefinedExplicit canvas width in CSS pixels. When omitted, the component uses the container's client width.
heightnumber | undefinedundefinedExplicit canvas height in CSS pixels. When omitted, the component uses the container's client height.
classNamestring | undefinedundefinedAdditional class names applied to the outer container div.
maxOpacitynumber | undefined0.3Maximum opacity assigned to a square when its opacity is initialized or refreshed.
...propsReact.HTMLAttributes<HTMLDivElement>undefinedAll other standard HTML attributes supported by a div, including id, style, data attributes, event handlers, and aria attributes; they are spread onto the outer container.

Accessibility

  • The component renders a canvas without text alternative, ARIA role, or accessible label; treat it as decorative background content.
  • When the grid is purely decorative, pass aria-hidden="true" to the component so assistive technologies can ignore its container.
  • The canvas has pointer-events-none, so it does not block interaction with content layered above it.
  • Animation starts only while the canvas intersects the viewport, reducing unnecessary work off-screen.
  • The source does not implement prefers-reduced-motion handling. If reduced motion is required, conditionally render or hide the component at the application level.
