Why did you build this? Because responsive CSS hasn’t really evolved in 10 years. Most frameworks either give you full control with too much verbosity (like Tailwind) or ready-to-use components that are too rigid (like Bootstrap). I wanted something in between — a system that’s adaptive by design, using native CSS features like container queries and custom properties. What’s new or unique? 🔹 A smart grid system that adapts to containers, not just viewports 🔹 Dynamic tokens (spacing, colors, type) driven by CSS variables 🔹 Fully CSS-native — no runtime JavaScript, no custom syntax 🔹 Ultra-lightweight: goal is ≤35KB in production, thanks to smart AST-based purging No build tool lock-in, no opinionated UI kit — just powerful primitives for modern teams and frontend developers who want both speed and control. What are you most proud of? I’m launching before writing a single line of code — to build with the community, not just for it. This is my first open-source design system from scratch, and I want to make it transparent, open, and pragmatic from day one.
