What practice helps ensure consistent theming across multiple pages?

• A. Centralize tokens and share across components using CSS variables, with page-specific overrides.
• B. Maintain tokens individually within each component to avoid cross-dependency.
• C. Hardcode color values in every component's stylesheet.
• D. Avoid using tokens; rely on inline styles for theming.

Answer: (A)

Centralized design tokens using CSS variables shared across components, with page-level overrides, keeps theming consistent across many pages. By storing colors, typography, and spacing as variables, every component references the same source of truth via var(--token-name). This means a single change to a token updates all components, ensuring a uniform look everywhere. You can apply global tokens at a root level and then override them for specific pages, giving each page its tweaks without touching every component. Other approaches that keep values inside each component or rely on hardcoded colors or inline styles break this coherence: they make global updates tedious, hinder theme switching, and increase the risk of visual drift.
