Summary

With theme variables in CSS: @theme { --color-brand-500: …; --font-display: …; --breakpoint-3xl: …; }. Each namespace creates utilities (bg-brand-500, font-display, 3xl:) and the values are also CSS variables usable anywhere. Reset a namespace with --color-*: initial.

Longer Answer

Prefer semantic names (primary, surface, danger) on top of a primitive palette so rebrands change values, not markup.

Key Points

  • @theme in CSS.
  • Namespaces create utilities.
  • Values are CSS variables.
  • Semantic naming.
