When theming across a page, how can you apply page-specific token overrides?

• A. Define page-specific tokens that override the global tokens via CSS variables.
• B. Remove all tokens on the page and rely on defaults.
• C. Implement token overrides by editing HTML elements directly.
• D. Use external images to simulate colors.

Answer: (A)

Page-specific token overrides are achieved by redefining design tokens as CSS custom properties on a page-level container. Because CSS variables cascade and are inherited, redefining the same token names inside a page wrapper (like a page class or a page-specific element) overrides the global values for all elements within that page, while leaving other pages unaffected. Define your tokens globally on the root, then on the page wrapper declare the same token names with new values. For example, set --color-bg and --color-text globally, and inside a specific page wrapper such as .page-about redeclare those tokens with the page-specific values. Elements inside that page will use the page-specific colors automatically. If a nested element redefines a token again, that nested value takes precedence, which gives you precise control when needed. Other approaches aren’t suitable here: removing tokens resets to defaults rather than page-specific overrides; editing HTML elements directly bypasses the token system and isn’t scalable; using external images to simulate colors defeats the purpose of a token-driven theme and doesn’t respond to token changes.
