Mobile-First Principles
- Tappable options: Big buttons, not tiny radio buttons
- One question per screen: No scrolling to see options
- Thumb-friendly: Primary actions in thumb zone
- Fast loading: Compress images, minimize scripts
Text Best Practices
- Short questions (under 50 characters)
- Short options (1-3 words ideal)
- Large, readable fonts (16px minimum)
Images on Mobile
- Compress aggressively (WebP format)
- 2x2 image grids work well
- Load above-the-fold images first
Testing
- Test on actual phones, not just responsive mode
- Test on slow connections (3G simulation)
- Test thumb reachability
