Mobile-first design prioritizes small screens as the starting point, ensuring core functionality works on all devices while leveraging larger screens for enhanced experience.
Minimal working example:
Mobile-First Approach:
Step 1: Design for Mobile (320px - 480px)
- Constrained space forces priorities
- Focus on essential content and actions
- Single column layout
- Touch-friendly interactive elements
Step 2: Enhance for Tablet (768px - 1024px)
- Add secondary content
- Multi-column layouts possible
- Optimize spacing and readability
- Take advantage of hover states
Step 3: Optimize for Desktop (1200px+)
- Full-featured experience
- Advanced layouts
- Rich interactions
- Multiple columns and sidebars
---
## Responsive Breakpoints:
Mobile: 320px - 480px
- iPhone SE, older phones
