Keyboard operability (keyboard-operability)

All interactive elements (e.g., buttons, links, forms, and menus) are accessible and usable via keyboard input alone.


Tabindex="-1" on iframe:

This <iframe> contains a visible "Home" link, but using <tabindex="-1"> removes it from keyboard navigation. As a result, keyboard users cannot access the link, which fails WCAG 2.1.1.


Note: Possible to automatically test. Automated tools can detect when an <iframe> contains interactive content and has <tabindex="-1">, which removes it from the tab order.
