This PR delivers comprehensive design specifications for modal focus management, stacking, and scroll lock behavior in Fluxora-Frontend. These specifications ensure consistent, accessible, and predictable modal interactions across all user flows and states.
Fluxora lacked a unified modal system with proper focus management and stacking behavior:
- Inconsistent focus management across modal components
- No modal stacking system for complex user flows
- Basic scroll lock implementation with layout shift issues
- Limited accessibility compliance for modal interactions
- Missing modal state management for nested scenarios
Created MODAL_FOCUS_MANAGEMENT_DESIGN_SPEC.md with:
- Modal classification (Primary, Secondary, System) with priority levels
- Complete state management (default, loading, empty, error, success)
- Focus management specifications with trap implementation and restoration
- Modal stacking system with z-index hierarchy (1100-1400)
- Scroll lock behavior with scrollbar compensation and position preservation
Delivered MODAL_IMPLEMENTATION_HANDOFF.md with:
- BaseModal component template with TypeScript interfaces
- useModalManager and useModalAccessibility hooks
- ModalManager and ScrollLockManager classes
- CSS module specifications using existing design tokens
- Migration guide for existing modal components
- WCAG 2.1 AA compliance requirements for all modal interactions
- Screen reader support specifications (NVDA, JAWS, VoiceOver, TalkBack)
- Keyboard navigation patterns and focus management
- ARIA implementation guidelines and testing procedures
- Smart Focus Trapping: Automatic focus trap with logical tab order
- Visual Stack Indicators: Backdrop opacity and scale changes for modal depth
- Seamless Scroll Behavior: Zero layout shifts when modals open/close
- Responsive Design: Mobile-optimized modal interactions
- Intelligent Focus Trap: Automatic focus trapping with restoration to trigger element
- Dynamic Focus Handling: Handle content changes and dynamically added elements
- Initial Focus Control: Configurable initial focus element for optimal UX
- Focus Group Prioritization: Primary actions prioritized over secondary elements
- Priority-Based Z-Index: Low (1100), Medium (1200), High (1300), Critical (1400)
- Visual Depth Indicators: Backdrop opacity and scale changes for stack depth
- LIFO Stack Management: Last In, First Out with priority override support
- Focus Transfer: Smooth focus transitions between stacked modals
- Reference Counting: Handle multiple modals without conflicts
- Scrollbar Compensation: Prevent layout shifts when hiding page scrollbars
- Position Preservation: Maintain scroll position across modal interactions
- Mobile Optimization: Handle touch scrolling and viewport changes
- WCAG 2.1 AA Compliance: Full accessibility compliance throughout
- Screen Reader Support: Comprehensive ARIA implementation
- Keyboard Navigation: Complete keyboard-only operation
- Visual Accessibility: High contrast, text scaling, reduced motion support
