Issue 001d: Responsive Design Implementation

Current Behavior

  • No responsive design considerations in HTML templates
  • Fixed-width layouts not optimized for mobile devices
  • No testing for various screen sizes and device types
  • Poetry content may be difficult to read on mobile

Intended Behavior

  • Mobile-first responsive design for optimal poetry reading
  • Clean, readable typography across all device sizes
  • Navigation elements adapt gracefully to mobile interfaces
  • Fast loading and accessible on all devices

Suggested Implementation Steps

  1. Mobile-First CSS: Design for mobile devices first, then enhance for desktop
  2. Typography Optimization: Ensure poetry content is readable across devices
  3. Navigation Adaptation: Mobile-friendly similarity navigation
  4. Touch Interface: Optimize for touch-based interactions
  5. Performance Testing: Validate loading speed on various devices
