Preguntas frecuentes

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.
