Green Border

Animated WebGL shader background in the Pulsing Border style. Default variant. Generated by the 21st.dev Shader Builder. Adapted from Paper Shaders under Apache-2.0. 5-color palette (#000000, #40FF00, #00FF11, #458F00, #13601A). Features: cursor-reactive (spotlight), high intensity. A drop-in, zero-dependency React component for hero sections and animated gradient/noise backgrounds.

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