Quick Reference

Stick to tabindex="0" for custom interactive elements
Use tabindex="-1" for elements that should only be focusable via script

Check

Check for any positive tabindex values and ensure custom interactive elements are focusable.

Fix

Remove positive tabindex values and use tabindex="0" or -1 appropriately.

Explain

Explain why positive tabindex values are problematic for keyboard navigation and user experience.
