Matrix Text
MatrixText animates text one character at a time, briefly replacing each non-space character with a random 0 or 1 before revealing the original character. It starts automatically after a configurable delay.

Usage
usage.tsx
import MatrixText from "@/components/kokonutui/matrix-text";export function MatrixTextExamples() { return ( <> <MatrixText /> <MatrixText text="ACCESS GRANTED" className="min-h-64 bg-black text-green-400" /> <MatrixText text="Welcome" initialDelay={500} letterAnimationDuration={700} letterInterval={80} /> </> );}- Add a Matrix-inspired reveal to a landing-page headline or short message.
- Create a terminal or cyber-themed visual accent.
- Animate a brief status, welcome message, or access-style heading.
- Use when an automatic, one-time character-by-character animation fits the page.
Examples
Default greeting
Show the default HelloWorld! animation.
default-greeting.tsx
import MatrixText from "@/components/kokonutui/matrix-text";export function Greeting() { return <MatrixText />;}Access message

access-message.tsx
import MatrixText from "@/components/kokonutui/matrix-text";export function AccessMessage() { return ( <MatrixText text="ACCESS GRANTED" className="min-h-64 bg-black text-green-400" /> );}Slower reveal
Adjust the initial wait, per-character reveal interval, and duration.
slower-reveal.tsx
import MatrixText from "@/components/kokonutui/matrix-text";export function WelcomeMessage() { return ( <MatrixText text="Welcome" initialDelay={500} letterAnimationDuration={700} letterInterval={80} /> );}API reference
PropTypeDefaultDescription
textstring"HelloWorld!"Text to reveal character by character. The animation and initial letter state are set up on mount.
classNamestring—Additional class names merged onto the outer wrapper, which includes centered flex layout and min-h-screen.
initialDelaynumber200Delay in milliseconds before the automatic animation starts.
letterAnimationDurationnumber500Duration in milliseconds that each non-space character remains in its binary state before resolving.
letterIntervalnumber100Interval in milliseconds between starting animations for successive characters.
Accessibility
- The outer wrapper has aria-label="Matrix text animation"; the component does not expose a prop to customize this label.
- The animated characters are rendered as individual motion divs, not as a dedicated live region. The source does not provide reduced-motion handling or an option to disable the animation.
- Keep the supplied text concise and ensure the message is also available in the surrounding page context for users who may not perceive the animation.
