常见问题
Quick answers.
›Does this tool store my HTML?
No. All checks are performed locally using a client-side parser, so your code never leaves your computer.
›Which WCAG version does this tool check against?
The checks are based on common WCAG 2.1 Level A and AA success criteria, specifically focusing on structural markup and descriptive elements.
›Does this handle dynamic or JavaScript-rendered content?
This tool is designed for static HTML fragments. For full dynamic pages, it is better to use browser-integrated developer tools that can inspect the live DOM.
›Will passing these checks make my site fully accessible?
Automated tools generally catch only 30-40% of accessibility issues. Use this as a first pass, then supplement with keyboard testing and screen reader verification.
