Frequently Asked Questions about a11y-audit

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I check my website for WCAG compliance issues?▼

You can check WCAG compliance by running script-based audits to identify color contrast failures, invalid ARIA labeling, incorrect landmark usage, keyboard navigation gaps, and semantic HTML errors across your web pages.

Can I batch scan multiple web pages for accessibility issues?▼

Yes, you can perform batch scans of multiple pages or components to enable scalable accessibility workflows. The audit process generates export-ready results for all scanned pages, producing a comprehensive batch report for remediation.

How does a color contrast checker validate WCAG standards?▼

A color contrast checker validates WCAG standards by analyzing the foreground and background color ratios on your web content. It uses script-based tools to calculate these ratios and flags elements that fail to meet the required visual accessibility thresholds.

Does this accessibility audit verify keyboard navigation and semantic HTML?▼

Yes, the accessibility audit explicitly verifies keyboard navigation and validates semantic HTML structure. It checks that web content is fully navigable via keyboard and that HTML elements are used correctly to convey meaning to assistive technologies.

What is the best way to automate ARIA labeling and landmark usage checks?▼

The best way to automate ARIA labeling and landmark usage checks is to run Python-based audit scripts that scan the HTML structure. These scripts detect missing or misapplied ARIA roles and landmark elements, returning export-ready results for remediation.

Do I need Python to run these WCAG accessibility scans?▼

Yes, you need Python to execute the script-based audits, such as running the contrast-checker.py and html-a11y-scan.py scripts. These Python tools process your web content to generate the accessibility violation reports.
