Tentang alat ini
Run quick accessibility checks against a page's HTML, flagging common issues that make a site harder to use for people with disabilities - like missing alt text on images, poor color contrast, or missing form labels. It's a fast first-pass audit, not a full replacement for comprehensive accessibility testing.

Common ones include missing image alt text, insufficient color contrast, missing form labels, and improper heading structure - the kinds of issues automated tools can reliably detect from HTML alone.
It ensures people with visual, motor, or cognitive disabilities can actually use your site, and is increasingly a legal/compliance requirement in many regions - beyond that, many accessibility fixes (like clear headings, good contrast) also improve usability for everyone.
