How It Works
How WCAG 2.2 Compliance Checking Works
1. HTML Parsing and Structure Analysis
The checker analyzes your HTML structure using advanced parsing:
- DOM Tree Analysis: Examines element relationships and hierarchy
- Semantic Structure: Validates proper use of headings, landmarks, and roles
- Form Structure: Checks form labels, fieldsets, and input associations
- Table Structure: Validates table headers, captions, and data relationships
2. WCAG 2.2 Success Criteria Evaluation
Comprehensive testing against WCAG 2.2 guidelines:
- Perceivable: Alt text, color contrast, text scaling, audio descriptions
- Operable: Keyboard navigation, seizure prevention, input modalities
- Understandable: Readable text, predictable functionality, input assistance
- Robust: Valid code, assistive technology compatibility
3. Automated Testing Rules
Advanced rule engine validates accessibility requirements:
- Image Analysis: Alt text presence, decorative image handling, complex images
- Color Testing: Contrast ratios, color-only information dependencies
- Keyboard Testing: Focus indicators, tab order, keyboard traps
- ARIA Validation: Proper roles, properties, and states usage
4. Report Generation and Recommendations
Intelligent reporting provides actionable insights:
- Issue Prioritization: Critical, serious, and moderate severity levels
- Fix Recommendations: Specific code examples and solutions
- WCAG References: Direct links to relevant success criteria
- Compliance Scoring: Percentage compliance for each WCAG level

Frequently Asked Questions
What's the difference between WCAG 2.1 and WCAG 2.2 compliance checking?
WCAG 2.2 includes all WCAG 2.1 requirements plus 9 additional success criteria focused on mobile accessibility, cognitive disabilities, and vision impairments. Key additions include Focus Not Obscured, Dragging Movements, Target Size (Minimum), and Fixed Reference Points for improved usability across devices and user needs.
Which WCAG compliance level should I target for my website?
Level AA is recommended for most websites and is required by laws like the ADA, Section 508, and EN 301 549. Level A provides basic accessibility but may not be sufficient for legal compliance. Level AAA offers the highest standard but can be difficult to achieve for all content - it's typically used for specialized accessible content.
Can this tool catch all accessibility issues or do I need manual testing?
This automated checker identifies approximately 30-40% of accessibility issues. Manual testing is essential for complete WCAG compliance, including keyboard navigation testing, screen reader testing, cognitive load assessment, and user experience evaluation with assistive technologies. Use this tool as a first step in your accessibility testing process.
How should I prioritize fixing the accessibility violations found?
Fix Critical violations first as they completely block access for users with disabilities. Address Serious issues next as they create significant barriers. Moderate issues can be planned for future updates. Focus on high-impact areas like navigation, forms, and main content before addressing decorative elements.
Does this checker work with React, Vue, Angular, and other JavaScript frameworks?
Yes, but paste the rendered HTML output rather than the framework source code. Use browser developer tools to copy the final DOM structure after JavaScript execution. For dynamic content, test different application states separately. Consider using accessibility testing tools integrated into your development workflow for framework-specific testing.
