Mobile-First Is Not Optional
Over 60% of web traffic is mobile. Responsive design ensures great experience everywhere.
Mobile-First Approach
Design for smallest screens first. Progressive enhancement adds features for larger screens. Forces content prioritization. Simplifies development.
Fluid Grids
Percentages replace fixed widths. Content adapts to container size. Breakpoints handle major layout shifts. Flexible images scale appropriately.
Media Queries
Breakpoints at common device widths. Min-width queries for progressive enhancement. Orientation queries for landscape/portrait. Feature queries for capability detection.
Typography
Relative units (rem, em) scale appropriately. Minimum 16px for body text on mobile. Line length limits for readability. Adequate contrast always.
Touch Targets
Minimum 44px touch targets. Adequate spacing between controls. Gesture-friendly interfaces. Eliminate hover-dependent interactions.
Testing
Device testing on real hardware. Browser dev tools simulation. Responsive design mode testing. User testing across devices.
Performance Considerations
Serve appropriately sized images. Conditional loading for heavy features. Network-aware enhancements. Battery-conscious animations.
Accessibility
Screen reader compatibility. Keyboard navigation. Focus indicators. Reduced motion support.
