Critical Level A WCAG 4.1.2 — Name, Role, Value

What’s wrong

An attribute starting with aria- doesn’t match any attribute defined in the ARIA spec, usually a typo like aria-lable instead of aria-label.

Why it matters

Browsers only recognize exact ARIA attribute names. A misspelled one is silently ignored, so the label or state never reaches assistive tech, and the element looks fine in a code review but fails for screen reader users.

How to fix it

Check the spelling against the ARIA spec and correct it.
