8.28 WCAG 2.2 Success Criterion 3.3.1 − Error Identification

If a user makes a mistake, use text to show user where and what user has done wrong, and how user can fix it.

Before Rectification

The example above shows an error has been identified without any information on where the error is and what needs to be fixed.

After Rectification

This is made accessible by telling the user where the error has occurred and what user needs to do to fix the error.
