CSS Variables Best Practices

  • Naming Convention: Use semantic names (color-primary) over specific values (color-blue)
  • Prefix: Add a prefix to avoid conflicts with other libraries
  • Scale System: Use consistent scales for spacing and typography
  • Dark Mode: Define variables per theme in separate selectors
  • Fallbacks: Use var(--color, fallback) for browser compatibility
  • Performance: CSS variables are inherited, place them on :root for global access
