Design systems are the backbone of modern digital products.
They allow designers and developers to speak the same language, keeping interfaces unified as features scale. Leveraging CSS variables alongside utility frameworks like Tailwind is the most efficient way to build design tokens that translate directly from Figma to code.
1. Creating Spacing and Typography Spans
Map your layout spacing directly to a base-8 scale (8px, 16px, 24px, 32px). This creates proportional balance. Define custom typography tokens for body text, subtitles, and headings using custom root variables so they adapt smoothly across viewport breakpoints.
2. Designing for Dark and Light Modes
Instead of hardcoding color variables, utilize semantic tokens like --color-background, --color-surface, and --color-primary. This enables you to toggle themes globally simply by changing color variables on the HTML body class.
3. Meeting WCAG Accessibility Criteria
Ensure that text colors meet the minimum WCAG AA contrast ratio of 4.5:1 against their backgrounds. Test your interface elements under high zoom levels and verify keyboard navigability to prevent user friction.
