What problem does it solve?
Provide practical patterns and techniques to build interfaces that adapt fluidly across device sizes, container contexts, and input types, reducing layout breakage and manual breakpoint maintenance.
Core Features & Use Cases
- Container queries for component-level responsiveness that react to parent size rather than viewport.
- Fluid typography and spacing using clamp and viewport-relative mathematics to create smooth scaling between sizes.
- CSS Grid and Flexbox responsive patterns, auto-fit/auto-fill grids, responsive images with art direction, and adaptive navigation and table patterns.
- Breakpoint strategy guidance, feature-query fallbacks, testing approaches, and performance/accessibility best practices for production-ready responsive systems.
- Use case: Convert a fixed-layout product catalog into a fluid grid with container-aware cards, responsive images, and accessible mobile navigation.
Quick Start
Build a responsive component by combining container queries, fluid typography with clamp, and a CSS Grid or auto-fit layout so it adapts across mobile, tablet, and desktop.
