If an input error is automatically detected and suggestions for correction are known, then the suggestions are provided to the user, unless it would jeopardize the security or purpose of the content.
If there is a form that produces error messages.
Cause an error to happen on a form, for example by submitting it with empty mandatory fields, setting a date far into the future or past or omitting an @ symbol in an email field. If there are no error messages, these checks are not applicable.
Check:
- error messages have clear and helpful instructions on what the problem is and how to fix it, for example, "Your date of birth cannot be in the future. Please select a date in the past."
- if it's difficult to know automatically there is an error or how to correct it
- if error suggestions could compromise security, for example on a failed login attempt
No difference
