What WCAG 3.3.3 Requires
When an input error is detected, and a suggestion for fixing it is known, the suggestion must be provided, unless doing so would compromise security or the purpose of the content.
Can AccessBell Test This Automatically?
Not fully. Like most WCAG criteria that depend on meaning or context, this one needs a person to judge. AccessBell's report lists it for manual review rather than marking it pass or fail automatically, so it never gets missed.
How to Test It by Hand
Trigger a common input error (a malformed email, a mismatched password) and check whether the message suggests how to fix it.
Common Failures
- An "Invalid email" error gives no example of a correctly formatted email address.
