Multi-device testing identified horizontal overflow on iPad Pro 11 (834px viewport) and text truncation issues across devices.

Changes

Tables

  • Changed table-layout: fixedauto for responsive width adjustment
  • Added overflow-x: auto wrapper for viewports < 900px
  • Applied word-wrap: break-word to cells

Code blocks

  • Added overflow-x: auto and max-width: 100%
  • Applied overflow-wrap: break-word to inline code

Container overflow prevention

  • Applied overflow-x: hidden to body, html, and main containers
  • Added max-width: 100% to all markdown content children
  • Added responsive handling for images, videos, iframes, Mermaid diagrams

Tablet optimizations (768-900px)

  • Reduced header link spacing and font sizes
  • Added content padding

Test Results

Verified zero horizontal overflow across all form factors:

  • Mobile: iPhone 12/Pro Max, Pixel 5, Galaxy S21
  • Tablet: iPad, iPad Pro 11 (834px ✓), iPad Pro 12.9
  • Desktop: HD, FHD, 4K

iPad Pro 11 before: scrollWidth > clientWidth (horizontal scroll)
iPad Pro 11 after: scrollWidth = clientWidth (834px = 834px)

Device Test Matrix

Mobile Devices ✅

  • iPhone 12 (390x844) - ✅ Layout working, minor text truncation
  • iPhone 12 Pro Max (428x926) - ⚠️ Text truncation (6 elements)
  • Pixel 5 (393x851) - ⚠️ Text truncation (6 elements)
  • Galaxy S21 (360x800) - ⚠️ Text truncation (6 elements)

Tablet Devices ⚠️

  • iPad (768x1024) - ⚠️ Text truncation (6 elements)
  • iPad Pro 11 (834x1194) - ⚠️ Horizontal overflow detected + text truncation (19 elements)
  • iPad Pro 12.9 (1024x1366) - ⚠️ Text truncation (10 elements)

Desktop Devices ✅

  • FHD Desktop (1920x1080) - ⚠️ Text truncation (6 elements)
  • 4K Desktop (2560x1440) - ⚠️ Text truncation (6 elements)

🟡 Warnings

1. Text Truncation Across All Devices

Severity: Low
Affected: All 9 devices tested
Details: Detected 6-19 elements with text truncation (text width exceeds container width). Most are minor and don't impact readability significantly.

Recommendation: Review elements with overflow: hidden or text-overflow: ellipsis to ensure important content isn't being cut off.

2. Horizontal Overflow on iPad Pro 11

Severity: Medium
Affected: iPad Pro 11 (834x1194)
Details: Page has horizontal scrolling capability due to content exceeding viewport width. This is unusual for this specific viewport size.

Recommendation: Investigate responsive breakpoints around 834px width. May be related to navigation menu, code blocks, or diagram widths.

3. Form Inputs Without Labels (Accessibility)

Severity: Medium
Affected: Quick Start page and likely others
Details: Found 3 form inputs without proper labels or aria-label attributes on the Quick Start page.

Recommendation: Add proper ARIA labels or associate inputs with label elements for better accessibility.


✅ What's Working Well

  1. Responsive Layout: Site adapts well to different screen sizes overall
  2. Search Functionality: Search modal opens and functions correctly on mobile devices
  3. Navigation: Header navigation and mobile menu work properly
  4. Mermaid Diagrams: Complex diagrams load and render correctly (verified on Architecture page)
  5. Interactive Elements: Buttons, links, and theme switcher all function as expected
  6. Performance: Pages load quickly with no significant performance issues

Screenshots

Screenshots for all device types have been captured and saved to the workflow artifacts:

  • mobile-iphone12-home.png
  • mobile-iphone12-search.png
  • ipad-pro-11-overflow.png
  • quick-start-page.png
  • Plus individual screenshots for each device type tested

Accessibility Findings

✅ Passing

  • Skip to content link present
  • Language attribute set (lang="en")
  • Proper heading hierarchy maintained
  • No images missing alt text
  • No empty links without aria-labels

⚠️ Needs Improvement

  • 3 form inputs without labels on Quick Start page (search inputs, theme selector)
    • These inputs need aria-label attributes or associated (label) elements

Recommendations

High Priority

  1. Fix horizontal overflow on iPad Pro 11 viewport
  2. Add aria-labels to unlabeled form inputs for accessibility compliance

Medium Priority

  1. Review and optimize text truncation across devices - ensure no critical content is being cut off
  2. Test with actual screen readers to verify accessibility improvements

Low Priority

  1. Consider adding visual regression testing to catch layout issues automatically
  2. Document responsive breakpoints and test them systematically

Technical Details

Build: Successful

  • 670 packages installed
  • 71 pages built
  • Pagefind indexed 70 pages, 5086 words
  • All internal links validated ✅

Testing Tools:

  • Playwright for cross-device testing
  • Accessibility audits for WCAG compliance checks
  • Layout overflow detection via JavaScript evaluation

Base URL: `(redacted)


Next Steps

  1. Address the horizontal overflow issue on iPad Pro 11
  2. Add accessibility labels to form inputs
  3. Consider running this automated test suite on each PR to catch regressions early

Note: All issues identified are minor and don't block the site from being used effectively. The documentation site is production-ready with these cosmetic improvements noted for future enhancement.
