CSS Variables and Design Tokens are transforming how we build scalable, themeable interfaces — and in 2025, they’re more important than ever.
I just published a complete guide covering how to use CSS Variables, global tokens, dynamic themes, and modern tooling to create flexible UI systems that actually scale.
What the guide covers:
- The difference between CSS Variables & Design Tokens
- How to structure tokens for color, spacing, typography, shadows
- Dynamic theming (light/dark/system) with JavaScript
- Token-driven component design
- How big teams maintain UI consistency
- Real-world examples and best practices
If you want to level up your CSS architecture and build theme-ready UI the right way, this guide is for you.
