Step-by-Step Guide to Testing Accessibility with Chrome DevTools

Step 1: Open Chrome DevTools

To access Chrome DevTools:

1. Open your WordPress site in Google Chrome.
2. Right-click anywhere on the page and select Inspect.
3. The DevTools panel will appear on the side or bottom of your browser.

Step 2: Navigate to the Lighthouse Tab

Lighthouse is Chrome DevTools’ built-in audit tool. To use it:

1. In the DevTools panel, click on the Lighthouse tab.
2. Select Accessibility as the audit category. You can also include Performance, SEO, and Best Practices for a broader analysis.
3. Click Generate Report to start the audit.

Step 3: Analyze the Lighthouse Report

Once the audit is complete, Lighthouse will generate a report with:

• Accessibility Score: A percentage score indicating your site’s accessibility level.
• Issues List: Detailed information on accessibility issues, such as missing alt text or low contrast ratios.
• Suggestions: Recommended fixes for each issue.

Step 4: Test Keyboard Navigation

Keyboard navigation is critical for users relying on assistive technologies. To test:

1. Press Tab to navigate through interactive elements like links and buttons.
2. Ensure the focus indicator is visible on each element.
3. Verify that the navigation order is logical and intuitive.

Step 5: Inspect ARIA Roles and Attributes

ARIA (Accessible Rich Internet Applications) roles and attributes provide additional context for assistive technologies. To check:

1. In DevTools, select the Elements tab.
2. Hover over elements in the DOM to view applied ARIA roles and attributes.
3. Ensure roles like aria-label, aria-describedby, and role are used appropriately.

Step 6: Test Color Contrast

Good color contrast is essential for readability. To test:

1. In the Elements tab, select a text element.
2. View the Styles pane to check computed color values.
3. Use the contrast ratio checker to ensure compliance with WCAG guidelines (minimum 4.5:1 for normal text).

Step 7: Debug and Fix Issues

For each issue identified in the Lighthouse report or manual tests, make the necessary updates. Common fixes include:

• Adding descriptive alt text to images.
• Improving keyboard navigation and focus indicators.
• Adjusting color contrast for better readability.

Best Practices for Accessibility Testing

• Test Regularly: Conduct accessibility audits after major site updates.
• Combine Tools: Use multiple tools like Axe, WAVE, and Lighthouse for comprehensive testing.
• Involve Users: Get feedback from individuals with disabilities to identify real-world issues.
