📊 Mobile Traffic & Accessibility
✅ 60%+ of all web traffic is now mobile
✅ 62% of ADA lawsuits mention mobile accessibility
⚠️ 85% of mobile websites have touch targets too small
Mobile Accessibility Testing Checklist
👆 Touch Target Size (WCAG 2.5.5)
Buttons, links, and interactive elements must be at least 44x44pt on mobile.
✅ Good: 48x48 button → Easy to tap
❌ Bad: 24x24 button → Hard to tap, ADA violation
Close buttons should have enough space to prevent accidental taps.
🔍 Screen Reader Testing
Settings → Accessibility → VoiceOver → Turn on. Then triple-click side button to toggle.
Settings → Accessibility → TalkBack → Turn on. Use two fingers to scroll.
⌨️ Keyboard Support (External Keyboard)
Test if users can navigate using Tab, Enter, arrow keys, and Escape.
📱 Orientation & Reflow
Rotate your device — does content adjust properly?
Pinch to zoom or use browser zoom — does content reflow to one column?
🎨 Color & Contrast on Mobile
Use color contrast checker — especially important for outdoor reading (sunlight).
Icons, buttons, and UI components must have sufficient contrast.
