Accessibility Checker for GitHub Markdown

The Accessibility Checker for GitHub Markdown is a powerful Chrome extension designed to improve the accessibility of your Markdown content on GitHub.com. It actively highlights accessibility issues such as missing 'alt' text on images, empty links, incorrect link syntax, skipped heading levels, duplicate headings, and more as you write in issues, pull requests, discussions, and comments. This real-time feedback helps developers and contributors ensure their content is inclusive and adheres to accessibility best practices.

Once installed, the extension works seamlessly within GitHub's Markdown editors, providing clear visual cues for detected issues. Users can navigate to or hover over highlighted items to get detailed information, making it easier to fix problems promptly. This tool is ideal for developers aiming to maintain high accessibility standards in their documentation and discussions on GitHub.
