Quick answers for Accessibility Checker

What does the Accessibility Checker actually inspect?
Paste in HTML and it parses the markup to flag missing image alt text, a missing lang attribute on the html tag, a missing page title, buttons and links without accessible names, form inputs without an associated label, and missing landmark elements like header, main, nav, and footer.
Does it measure contrast or certify WCAG compliance?
No. It checks static HTML only. It does not measure rendered contrast or test keyboard navigation, focus order or runtime behavior. Manual accessibility review is still needed.
Do I need to give it a live URL?
No. Paste raw HTML directly into the tool and it parses it with the browser's built-in DOMParser, so you can check a page before it's even deployed.
