Responsive Strategies #

Mobile-First Approach #

  4. Test at each breakpoint

Desktop-First Approach #

  1. Design full desktop experience
  2. Simplify for tablet
  3. Stack for mobile
  4. Verify all content accessible

Inheritance Best Practices #

  • Set base styles on desktop
  • Override only what changes
  • Let values cascade down
  • Clear to restore inheritance

Advanced Techniques #

Nested Containers #

Create complex layouts:

  1. Outer container for page structure
  2. Inner containers for sections
  3. Nested flex for fine control
  4. Different directions at each level

Responsive Visibility #

Show different layouts per device:

  1. Desktop container with 3 columns
  2. Tablet container with 2 columns
  3. Mobile container with accordion
  4. Use display settings to show/hide

Performance Optimization #

  • Hide unnecessary elements on mobile
  • Reduce shadows and effects on small screens
  • Simplify layouts for better performance
  • Test on real devices

Accessibility Patterns #

  • Provide adequate touch targets

Styling Best Practices #

Color Usage #
