What problem does it solve?
Adapting designs to different screen sizes, input methods, and usage contexts so interfaces remain usable, accessible, and effective when moved between desktop, mobile, tablet, print, or email. It reduces broken layouts, unusable interactions, and poor content prioritization that occur when a design is simply scaled instead of rethought for a new context.
Core Features & Use Cases
- Context assessment: Identify source assumptions (input method, connection, screen size) and gather target platform details before making changes.
- Layout & interaction strategies: Prescribes single-column stacking, bottom navigation, touch target sizing (44x44px), container queries, CSS Grid/Flexbox, and breakpoint planning.
- Platform-specific adaptations: Guidance for mobile-first reflows, tablet master-detail, desktop enhancements (hover, shortcuts), print-friendly pagination, and email-safe single-column layouts.
- Verification checklist: Emphasizes real-device testing, orientation checks, accessibility, and slow-network simulations.
Quick Start
Adapt the homepage from desktop to mobile by prioritizing primary content, switching to a single-column layout, using 44x44px touch targets, and defining breakpoints around 375px and 768px.
