9.12 Level AA − WCAG 2.0 Success Criterion 3.3.3 − Error Suggestion

When a user makes an error and the solution can be identified automatically, always provide the user with a suggestion to fix the error.

Before Rectification

A webpage sample with a generic error message displayed at the bottom of a form containing input errors.

The example above shows an error message that is not helpful enough because it is located at the bottom of the webpage, and does not provide an adequate description of what needs to be corrected.

After Rectification

A webpage sample with a detailed error message displayed at the top of a form.

In contrast, this example shows a message that is located at the top of the webpage and provides a good explanation of what needs to be corrected.
