Responsive Design Principles

Status: ✅ Last Validated: 2025-01-02

Purpose

Invoked when creating responsive layouts or optimizing SARAISE UI for mobile/tablet devices. Provides mobile-first design principles aligned with Tailwind CSS breakpoints and SARAISE design system.

Mobile-First Approach

  • •Design for mobile first, then scale up
  • •Progressive enhancement over graceful degradation
  • •Touch targets minimum 44x44px
  • •Avoid hover-only interactions
  • •Test on real devices

Breakpoints (Tailwind CSS)

  • •sm: 640px (mobile landscape) - @media (min-width: 640px)
  • •md: 768px (tablet portrait) - @media (min-width: 768px)
  • •lg: 1024px (tablet landscape / small desktop) - @media (min-width: 1024px)
  • •xl: 1280px (desktop) - @media (min-width: 1280px)
  • •2xl: 1536px (large desktop) - @media (min-width: 1536px)

Fluid Typography

  • •Use rem for font sizes
  • •Base size: 16px
  • •Scale: 1.125 (major second) or 1.2 (minor third)
  • •Use clamp() for fluid scaling
  • •Line length: 45-75 characters optimal

Flexible Layouts (Tailwind)

  • •Use grid classes for page layouts (grid-cols-1 md:grid-cols-2 lg:grid-cols-3)
  • •Use flex classes for component layouts (flex flex-col md:flex-row)
  • •Avoid fixed widths, use w-full with max-w-*
  • •Content containers: max-w-7xl mx-auto px-4 sm:px-6 lg:px-8
  • •Use gap-* instead of margins in flex/grid (gap-4, gap-6)

Images & Media

  • •Use responsive images (srcset, sizes)
  • •Use object-fit for aspect ratios
  • •Lazy load below-the-fold images
  • •Optimize for different densities (@1x, @2x)
  • •Use CSS for simple graphics

Common Patterns

  • •Hamburger menu for mobile navigation
  • •Card layouts that stack on mobile
  • •Side-by-side columns that stack
  • •Hidden elements on mobile (use wisely)
  • •Bottom navigation on mobile apps

Testing

  • •Test on actual devices
  • •Use browser DevTools device mode
  • •Test at various viewport sizes
  • •Test with slow connections
  • •Test landscape and portrait orientations
