Responsive Design and Device Strategy Questions

Covers designing user interfaces and front end architectures that adapt gracefully across a wide range of screen sizes and device types. Topics include breakpoint strategy, fluid and adaptive layout patterns, component adaptation rules, progressive enhancement, handling single column to multi column transitions, touch and pointer interactions, performance implications for mobile versus tablet and desktop, and accessibility considerations. At senior levels include how to scale responsive approaches across teams and products: design systems and component libraries that enforce responsive behavior, guidelines for consistency, testing strategies across form factors, build and release coordination, and measuring success through metrics such as perceived performance and device specific engagement.
