Cyberpunk Glitch Button

A futuristic button featuring a neon glow and subtle glitch animation that looks great in dark mode.

HTMLCSS

Preview

A button featuring neon colors and a hover glitch effect, perfect for dark themes or sci-fi-inspired UIs.

Use Cases and Features

  • Cyberpunk and Sci-Fi Design: Ideal for game UIs, Web3-related sites, creative portfolios, and projects where you want to evoke an extraordinary or futuristic atmosphere.
  • Neon Glow and Glitch: On hover, the base color shifts and an aggressive glitch (bug) animation is triggered, delivering a strong visual impact to the user.
  • Shapes Powered by CSS clip-path: The distinctive shape with “chipped” corners is created entirely using clip-path rather than images, ensuring it is lightweight and fully responsive.

Design and UX Insights

  1. Visual Feedback: The dramatic change on hover (a color shift from cyan to magenta along with a glow) clearly communicates that the element is interactive.
  2. Multi-Layer Structure: By combining ::before, ::after, and a decorative element (.decoration), it achieves a framed design with a sense of depth.
  3. Accessibility Considerations: The duplicated text used for the glitch effect is given aria-hidden="true" to prevent it from interfering with screen readers.

Customization Guide

By simply changing the CSS variables, you can create a cyberpunk button tailored to your project’s theme colors.

.cyber-btn {
  /* メインカラー（通常時の色） */
  --primary-color: #00ffcc;
  
  /* セカンダリカラー（ホバー時の色） */
  --secondary-color: #ff00ff;
  
  /* 背景色（内側の暗い部分） */
  --bg-color: #050505;
}

Using a monospaced font (monospace) further enhances the hacking UI or system console aesthetic.
