Implemented responsive mobile card layouts for all main Index views, providing superior mobile UX while maintaining desktop table views.
**Responsive Design Pattern:**
- Desktop (≥992px): Table layout with all data columns
- Mobile (<992px): Card-based layout optimized for touch interaction
- Breakpoint: Bootstrap's lg breakpoint for optimal viewing experience
**Views Converted:**
1. **Categories/Index.cshtml:**
- Mobile cards with name, description, product count, status
- Full-width action buttons for easy touch interaction
- Clear visual hierarchy with icons and badges
2. **Users/Index.cshtml:**
- Simplified mobile cards showing username, created date, status
- Conditional delete button (protected admin account)
- Clean, minimal design for quick user management
3. **ShippingRates/Index.cshtml:**
- 2x2 grid layout for shipping rate data (country, price, weight, delivery)
- Visual separation with light background boxes
- All critical information displayed in scannable format
4. **VariantCollections/Index.cshtml:**
- Properties JSON displayed in scrollable code block
- Created/Updated dates in compact format
- Clear deactivation action for variant collections
**Mobile UX Enhancements:**
- ✅ 44px minimum touch targets (Bootstrap .btn default)
- ✅ Full-width buttons with .d-grid gap-2 for easy tapping
- ✅ Proper spacing with mb-3 between cards
- ✅ Clear visual hierarchy with card-title and badges
- ✅ Descriptive button text (not just icons) on mobile
- ✅ Responsive icons and status indicators
- ✅ Word-break handling for long JSON strings
**Technical Implementation:**
- Used Bootstrap's d-none d-lg-block for desktop tables
- Used d-lg-none for mobile card views
- No JavaScript required - pure CSS responsive design
- Maintains all functionality from desktop view
- Zero data loss in mobile transformation
**Accessibility Maintained:**
- All ARIA labels preserved from Phase 1
- Semantic HTML structure in both views
- Proper heading hierarchy maintained
- Keyboard navigation fully functional
