Theming
Themes are plain TypeScript objects compiled into --z-* CSS custom properties. Switching a theme rewrites variables — instantly, no CSS-in-JS, no re-render cost for styles.
Ready-made themes
import { lightTheme, darkTheme, auraTheme, materialTheme } from "@zephora/theme";createTheme
import { createTheme, lightTheme } from "@zephora/theme";
const brand = createTheme(lightTheme, {
name: "brand",
colors: {
primary: "#0f766e",
primaryHover: "#115e59",
ring: "#14b8a6",
},
radius: "0.75rem",
});Scoped vs global
// Scoped — wraps a subtree in a themed scope element
<ThemeProvider theme={brand}>...</ThemeProvider>
// Global — writes variables onto <html>, ideal for app-level switching
import { applyTheme } from "@zephora/theme";
applyTheme(brand);CSS-level overrides
Components read variables directly, so any CSS rule can retheme any subtree:
.marketing-section {
--z-primary: #ea580c;
--z-radius: 9999px;
}Dark mode
const [scheme, setScheme] = useState<"light" | "dark">("light");
<ThemeProvider theme={scheme === "dark" ? darkTheme : lightTheme} global>
<App />
</ThemeProvider>
