F76: Failure of Success Criterion 3.2.2 due to providing instruction material about the change of context by change of setting in a user interface element at a location that users may bypass


Applies to all technologies.

This failure relates to:


Without prior instruction, unexpected change of context due to change of user interface setting can sometimes confuse users. Users must receive instruction prior to such encounter. Providing the instruction in a way in which the user may not have the opportunity to review may leave opportunity for confusion.

Failure examples:



  1. Find occurrence of change of context due to change of user interface setting

  2. Find instructional material that all users must review prior encountering of the change of context.

Techniques are Informative

Techniques are informative—that means they are not required. The basis for determining conformance to WCAG 2.0 is the success criteria from the WCAG 2.0 standard—not the techniques.
