Matte Textarea Input

A floating-label textarea that auto-grows with its content, shows a live character counter against a max length, and swaps its helper text when the limit is reached. Ported to React from the original HTML/CSS/JS component by SLtowl (sl-ui-library).

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