How do design tokens support maintainable CSS?

• A. They centralize values for colors, typography, and spacing to ensure consistency and allow easy theming.
• B. They duplicate style values across components.
• C. They restrict CSS to only one property per file.
• D. They are used only in JavaScript, not CSS.

Answer: (A)

Design tokens centralize values for colors, typography, and spacing into a single reusable set that feeds all CSS across a project. This creates a single source of truth, so updating a token—like a primary color, a font scale, or a spacing unit—propagates everywhere, ensuring consistency and reducing the risk of drift. Tokens also make theming straightforward: switch token values to change the look for different brands or modes without touching individual styles. This approach scales beyond colors and typography to borders, radii, and shadows, keeping design decisions centralized and easier to maintain across components and systems. Tools can expose tokens as CSS variables or consume them in CSS-in-JS or preprocessors, but the underlying idea is a centralized, reusable set of design values that promotes consistency and easy updates.
