Extra Explanation
Why This Matters
CSS Dark Mode and Theme Switching helps you build visual consistency. Reusable classes and a predictable spacing system make interfaces faster and cleaner to build.
Real-World Workflow
Teams usually begin with design tokens for colors, spacing, and type scale. This keeps new components consistent and avoids random values.
Common Mistakes to Avoid
Over-specific selectors, excessive !important use, and mixed units create avoidable bugs. Mobile-first CSS keeps responsive behavior more stable.
