AltF Security questions and answers

What does the AltF Security audit actually check?

Document language, a non-empty title, viewport metadata, exactly one H1, heading levels that do not skip, an alt attribute on every image, an accessible name on every link and button, and a label association for every visible form field. Each failing check returns the remediation to apply.

Can I give AltF Security a URL instead of HTML?

No. The audit takes pasted markup only. Copy the rendered HTML from your browser's developer tools or view-source, then paste it into the field.

Is passing this audit the same as being WCAG compliant?

No. These are automated structural checks. Automated testing can only cover a minority of WCAG success criteria, and the rest - meaningful alt text, logical focus order, understandable error messages - require manual review.
