Mobile Optimizations Summary

🎯 Overview

Comprehensive mobile optimizations to prevent crashes, improve performance, and ensure excellent UX on mobile devices.

✅ Implemented Fixes

1. Mobile Detection & Performance (assets/js/mobile-optimizer.js)

  • ✅ Robust mobile detection (touch support, screen size, user agent, hover capability)
  • ✅ Safe console wrapper to prevent crashes when console is disabled in production
  • ✅ Automatic disabling of heavy features on mobile:
    • Terminal components
    • Video preview system
    • Post preview tooltips
    • Heavy animations
  • ✅ GSAP and ScrollTrigger optimizations for mobile
  • ✅ Global mobile flags for conditional feature loading

  • ✅ Mobile typography scaling with clamp()
  • ✅ Navigation mobile enhancements (fixed menu, better spacing)
  • ✅ Card and content mobile improvements
  • ✅ Hero section mobile fixes
  • ✅ Masonry grid mobile enhancements

  5. GSAP autoSleep enabled

Layout Optimizations

  1. No horizontal scroll (100vw replaced with 100%)
  2. Fixed positioning handled properly
  3. Touch-friendly spacing and sizing
  4. Reduced shadow complexity
  5. Simplified glassmorphic effects on low-end devices

📝 Implementation Details

Load Order (Critical!)

1. Mobile Optimizer JS (first script)
2. normalize.css
3. bulma.min.css
4. mobile-critical-fixes.css (NEW)
5. Core CSS files
6. Component CSS files
7. GSAP (with mobile config)
8. Other libraries (conditionally)

Mobile Detection

// Checks multiple factors:
- Touch support (ontouchstart, maxTouchPoints)
- Screen size (width <= 768px)
- User agent (mobile device detection)
- Hover capability (CSS media query)

Conditional Loading

if (!window.IS_MOBILE) {
  // Load heavy features
  - Terminal
  - Video Preview
  - Post Preview
}

🧪 Testing Checklist

Mobile Testing

  • Test on iOS Safari (iPhone)
  • Test on Android Chrome
  • Test on iPad
  • Test horizontal scrolling
  • Test touch targets (minimum 44x44px)
  • Test form inputs (no zoom on focus)
  • Test navigation menu
  • Test image galleries
  • Test swiper carousels
  • Test safe area insets (iPhone X+)

Performance Testing

  • Check initial load time
  • Monitor memory usage
  • Test scroll performance
  • Verify animations are smooth
  • Check for layout shifts (CLS)
  • Test on slow 3G connection
