Course syllabus:

CHAPTER 1: Accessibility Remediation Strategies

This chapter guides developers and testers through fixing common WCAG Level AA issues with practical, role-specific solutions.

1.1 Remediating Semantic C Structural Issues

• Use semantic HTML (, , , )
• Replace / with meaningful elements
• Maintain proper heading hierarchy (H1 → H2 → H3)
• Add ARIA roles only when necessary

1.2 Remediating Keyboard C Focus Issues

• Ensure all interactive elements are reachable via Tab
• Fix focus traps in modals and custom widgets
• Add visible focus indicators using CSS
• Use to manage focus order

1.3 Remediating Color C Contrast Failures

• Use contrast checkers to meet 5:1 ratio
• Avoid color-only indicators (e.g., red = error)
• Add icons, labels, or patterns for clarity
• Ensure hover/focus states meet contrast requirements

1.4 Remediating Form C Error Handling

• Use linked to inputs via and
• Provide clear instructions and inline error messages
• Use for error associations
• Avoid CAPTCHA or provide accessible alternatives

1.5 Remediating Dynamic C ARIA Content

• Use for dynamic updates
• Ensure ARIA roles match element purpose
• Avoid redundant/conflicting ARIA attributes
• Test with screen readers (JAWS, NVDA, VoiceOver)

CHAPTER 2: Mobile Accessibility Testing

This chapter focuses on WCAG compliance and usability testing for mobile apps and responsive web interfaces.

2.1  Mobile-Specific WCAG Guidelines

• Orientation: Support both portrait and landscape
• Reflow: Avoid horizontal scroll at 400% zoom
• Pointer Gestures: Avoid multi-point gestures
• Motion Actuation: Provide alternatives to shake/tilt
• Target Size: Minimum 24x24px for touch targets

2.2 Mobile Testing Techniques

• Use screen readers (TalkBack, VoiceOver)
• Test zoom and reflow at 400%
• Navigate using external keyboards
• Simulate color blindness and low vision

2.3 Mobile Testing Tools

• Accessibility Scanner (Android)
• VoiceOver Rotor (iOS)
• Browser DevTools with mobile emulation
• Axe DevTools Mobile
• Lighthouse Mobile Audit

2.4 Common Mobile Accessibility Issues

• Small or overlapping touch targets
• Missing labels on icons or buttons
• Poor contrast in bright environments
• Inaccessible gestures or animations

2.5 Mobile Remediation Tips

• Use scalable units (em, rem, %) for layout
• Avoid fixed pixel widths
• Ensure all buttons/icons have accessible names
• Provide keyboard and screen reader support for all features

CHAPTER 3: PDF Accessibility Testing

This chapter equips testers and developers with the knowledge and tools to evaluate and remediate PDF documents for accessibility.

3.1 What Makes a PDF Accessible?

• Tagged content structure (headings, paragraphs, lists)
• Logical reading order
• Searchable text (not scanned images)
• Proper use of document language and metadata
• Compatibility with screen readers and assistive tech

3.2 WCAG Guidelines Relevant to PDFs

• Non-text Content: Alt text for images and icons
• Info and Relationships: Use tags for headings, lists, tables
• Meaningful Sequence: Reading order must match visual order
• Page Titled: Title metadata must be descriptive
• Language of Page: Set document language in properties

3.3 How to Test PDF Accessibility

• Use Adobe Acrobat Pro’s Accessibility Checker
• Use PAC 2021 (PDF Accessibility Checker) for WCAG compliance
• Use screen readers (JAWS, NVDA) to test reading order and tag structure
• Manually inspect tags, reading order, and alt text
• Validate metadata and document properties

3.4 Common PDF Accessibility Issues

• Missing or incorrect tags (e.g., headings as paragraphs)
• Unlabeled form fields or buttons
• Images without alt text
• Incorrect reading order
• Scanned documents without OCR

3.5 Remediation Techniques

• Use Adobe Acrobat Pro to add and fix tags
• Use “Reading Order” tool to adjust flow
• Add alt text to images via tag properties
• Set document language and title in metadata
