Underline Icon

An animated underline icon that plays a letter-wobble and line-squeeze animation on hover or via an imperative ref, for toolbars and text-formatting UI.

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

import { UnderlineIcon } from "@/components/ui/lu-underline";

export default function UnderlineIconDemo() {
  return (
    <div className="flex items-center justify-center w-full h-full min-h-[200px]">
      <UnderlineIcon size={64} duration={1} />
    </div>
  );
}
