About

An animated code block with syntax highlighting, copy-to-clipboard, line highlighting and an optional typing reveal animation.

Built with React and Tailwind. Copy the prompt and paste it into Claude Code, Cursor or Lovable: your agent adds Code Block to your project and fits it to your theme.

Code

How Code Block is used: the demo's code. The component's own source comes with a free account.

Usage.tsx

import CodeBlock from "@/components/ui/code-block";

const sample = `import { useState } from "react";

export function Counter() {
  const [count, setCount] = useState(0);

  return (
    <button onClick={() => setCount(count + 1)}>
      Clicked {count} times
    </button>
  );
}
`;

export default function CodeBlockDemo() {
  return (
    <div className="w-full max-w-lg">
      <CodeBlock
        code={sample}
        language="tsx"
        filename="counter.tsx"
        highlightLines={[4]}
      />
    </div>
  );
}
