1. Mobile-First Is the Standard in 2025 (Not Just an Option)

What Is Mobile-First Design? 

Unlike “responsive” design (which adapts desktop layouts to mobile), mobile-first means: 

• Designing for small screens first, then scaling up 
• Prioritizing thumb-friendly navigation 
• Optimizing for instant-loading and offline access 

Example: 

• ❌ Old Approach: Desktop site → shrunk for mobile (slow, clunky) 
• ✅ Mobile-First: Built for smartphones → expanded for desktop (fast, intuitive)

• Problem: PWAs increase engagement by 137% (Forrester) 
• Fix:
