Implementing Multi-Brand Theming with CSS Variables

Switch between multiple brand themes at runtime by swapping CSS custom property values.

Theme Architecture Overview

Multi-brand theming maps a single set of component alias tokens to different global token values per brand. Components reference alias tokens; brand theme files remap aliases to brand-specific globals.

Base Token Layer

Define global tokens in :root: all raw color values, spacing values, and typography values. This is the default brand. Components never reference globals directly — always through aliases.

:root {
  --color-brand-primary: #3b82f6;
  --color-brand-secondary: #10b981;
}
