You can build a responsive UI by combining container queries for component-level responsiveness, clamp-based fluid typography for scaling text across viewports, and CSS Grid for composing adaptable mobile-first layouts.

Container queries are a CSS feature enabling component-level responsiveness based on container size. You need them for responsive web design when designing systems where components must reflow gracefully from mobile to desktop without relying on global breakpoints.

Yes, you can use CSS Grid and fluid typography for a mobile-first design system. CSS Grid composes robust adaptable layouts while clamp-based fluid typography ensures text scales gracefully, allowing components to reflow without global breakpoints.

The best way to scale text across viewports in responsive design is using fluid typography. By leveraging the CSS clamp() function, text scales gracefully across different screen sizes without requiring manual breakpoint adjustments.

You should use container queries instead of global breakpoints for component libraries because container queries enable component-level responsiveness based on the container size, ensuring components reflow gracefully from mobile to desktop independently.
