Accessibility Inspector: Ensure Web Accessibility Compliance
Web accessibility isn't just a best practice—it's a legal requirement and a moral imperative. Ensuring your websites are accessible to everyone, including users with disabilities, is crucial for inclusive design. The Accessibility Inspector checks ARIA roles, labels, alt text, and accessibility compliance on hover, making it easy to identify and fix accessibility issues.
What is the Accessibility Inspector?
The Accessibility Inspector is a powerful accessibility auditing tool that's part of the UI Developer Toolkit Chrome Extension. It provides instant accessibility information by hovering over elements, checking ARIA roles, labels, alt text, and other accessibility attributes—all without leaving the page you're working on.
Whether you're conducting accessibility audits, ensuring WCAG compliance, or building inclusive interfaces, the Accessibility Inspector provides the insights you need to create accessible web experiences for all users.
Key Features
1. ARIA Role Detection
The Accessibility Inspector automatically detects and displays ARIA attributes:
- ARIA Roles: Identifies ARIA roles (button, navigation, banner, etc.)
- ARIA Properties: Displays ARIA properties (aria-label, aria-labelledby, etc.)
- ARIA States: Shows ARIA states (aria-expanded, aria-hidden, etc.)
- Role Semantics: Verifies semantic HTML roles
This comprehensive ARIA analysis helps you understand how elements are exposed to assistive technologies.
2. Label Verification
The tool verifies that interactive elements have proper labels:
Label Checks:
- Form input labels (associated labels or aria-label)
- Button labels (text content or aria-label)
- Link text (descriptive link text)
- Image alt text (descriptive alt attributes)
Missing or insufficient labels are highlighted, making it easy to identify and fix labeling issues.
3. Alt Text Analysis
The Accessibility Inspector checks image accessibility:
- Alt Text Presence: Identifies images with missing alt attributes
- Alt Text Quality: Checks if alt text is descriptive and meaningful
- Decorative Images: Identifies decorative images that should have empty alt
- Alt Text Redundancy: Flags redundant alt text
Proper alt text is essential for screen reader users to understand image content.
4. Hover Inspector
The Accessibility Inspector provides instant accessibility information by hovering over elements:
- ARIA roles and properties
- Label information
- Alt text for images
- Accessibility issues and warnings
- Compliance status
No need to manually inspect elements or dig through HTML. Just hover and see all accessibility information instantly.
5. Compliance Checking
The tool automatically checks for common accessibility issues:
- Missing Labels: Identifies unlabeled interactive elements
- Missing Alt Text: Flags images without alt attributes
- Poor Semantics: Identifies semantic HTML issues
- ARIA Misuse: Detects incorrect ARIA usage
Understanding Web Accessibility
WCAG Principles
Web Content Accessibility Guidelines (WCAG) are organized around four principles:
POUR Principles:
- Perceivable: Content must be perceivable by all users
- Operable: Interface components must be operable
- Understandable: Information must be understandable
- Robust: Content must be robust and compatible with assistive technologies
ARIA Roles and Attributes
ARIA (Accessible Rich Internet Applications) provides additional semantic information:
- Roles: Define what an element is or does
- Properties: Provide additional information about elements
- States: Indicate current state of elements

- Alt text for images
- Accessibility warnings or errors
Real-World Use Cases
1. Accessibility Audits
Conducting comprehensive accessibility reviews:
- Page-Wide Audits: Check all interactive elements systematically
- Identify Issues: Find accessibility violations quickly
- Document Problems: Record accessibility issues for remediation
- Verify Fixes: Confirm accessibility improvements meet standards
2. Form Accessibility
Ensuring forms are accessible:
- Label Verification: Ensure all inputs have proper labels
- Error Messages: Check error message association
- Required Fields: Verify required field indicators
- Fieldset Groups: Check form field grouping
3. Navigation Accessibility
Verifying navigation is accessible:
- Landmark Roles: Check navigation landmarks
- Link Labels: Verify descriptive link text
- Skip Links: Ensure skip links are present
- Keyboard Navigation: Verify keyboard accessibility
4. Image Accessibility
Ensuring images are accessible:
- Alt Text: Verify all images have appropriate alt text
- Decorative Images: Ensure decorative images have empty alt
- Descriptive Text: Check alt text quality and descriptiveness
- Complex Images: Identify images needing long descriptions
5. Legal Compliance
Meeting legal accessibility requirements:
- ADA Compliance: Ensure Americans with Disabilities Act compliance
- Section 508: Verify Section 508 standards
- EU Accessibility Act: Meet European accessibility regulations
- Documentation: Maintain records of accessibility testing
Benefits
Time Savings
Traditional accessibility checking requires:
- Opening DevTools
- Navigating to Accessibility panel
- Selecting each element individually
- Manually checking ARIA attributes
- Verifying labels and alt text
With the Accessibility Inspector:
- Hover over elements
- See all accessibility information instantly
Time saved per audit: 1-2 hours
Instant feedback vs. manual checking for every element
Comprehensive Coverage
The Accessibility Inspector provides:
- Complete ARIA Analysis: All ARIA roles, properties, and states
- Label Verification: Automatic label checking
- Alt Text Analysis: Comprehensive image accessibility checks
- Issue Detection: Automatic identification of common problems
Best Practices
1. Check During Development
Test accessibility early in the development process to avoid costly fixes later.
2. Test All Interactive Elements
Verify accessibility for all buttons, links, form inputs, and interactive components.
3. Use Semantic HTML
Prefer semantic HTML elements over ARIA when possible. ARIA should supplement, not replace, semantic HTML.
4. Test with Screen Readers
While the Accessibility Inspector provides valuable insights, always test with actual screen readers for real-world experience.
Conclusion
The Accessibility Inspector is an essential tool for creating inclusive web experiences. It combines comprehensive accessibility analysis with an intuitive hover inspector, making accessibility verification effortless and fast.
