About the CSS Variables Generator

Modern web development relies heavily on design tokens and CSS custom properties (variables) to maintain consistent theming across applications. This tool bridges the gap between raw color palettes and production-ready CSS.

Instead of manually typing out long lists of variables and media queries for dark mode, you can use this generator to output clean, perfectly formatted code ready to be pasted into your project's main stylesheet.

Example Output

:root {
  --color-primary: #6366f1;
  --color-secondary: #ec4899;
  --color-background: #ffffff;
}

:root.dark {
  --color-primary: #818cf8;
  --color-secondary: #f472b6;
  --color-background: #121212;
}
