className="font-semibold">Components</h3> + <Button>Primary Button</Button> + <Button variant="secondary">Secondary Button</Button> + <Button variant="outline">Outline Button</Button> + </div> + </div> + ) +} +``` + +## Best Practices + +1. **Design Token Organization** + - Use semantic naming (primary, secondary, not blue, red) + - Maintain consistent naming conventions + - Group related tokens together + - Version your design tokens + +2. **Color Accessibility** + - Test contrast ratios for all color combinations + - Ensure colors work for colorblind users + - Don't rely solely on color to convey information + - Provide sufficient contrast in both themes + +3. **Performance Optimization** + - Use CSS custom properties for runtime changes + - Avoid inline styles for theme values + - Minimize CSS-in-JS overhead + - Cache theme calculations + +4. **Developer Experience** + - Provide TypeScript types for theme tokens + - Include theme documentation + - Create theme development tools + - Maintain consistent API patterns + +Remember: Great themes are invisible to users but make everything feel cohesive and professional!
