Key Recommendations

  • Use utility classes directly in markup - Compose designs by combining utilities
  • Customize with theme variables - Use @theme directive to define design tokens
  • Mobile-first responsive design - Use unprefixed utilities for mobile, prefixed for breakpoints
  • Use complete class names - Never construct classes dynamically with string interpolation
  • Leverage variants - Stack variants for complex conditional styling
  • Prefer CSS-first configuration - Use @theme, @utility, and @custom-variant over JavaScript configs
