3.3.3 - Error suggestion
The intent of this success criterion is to ensure that users receive appropriate suggestions for correction of an input error if it is possible. The WCAG 2.0 definition of "input error" says that it is "information provided by the user that is not accepted" by the system. Some examples of information that is not accepted include information that is required but omitted by the user and information that is provided by the user but that falls outside the required data format or allowed values.
Ways to meet the criterion
Ensure that if an input error is detected (via client-side or server-side validation), provide suggestions for fixing the input in a timely and accessible manner.
UNLESS it would jeopardize:
- security
- purpose of the content i.e. an exam
