Level AA Perceivable
Operational summary
IF content supports display and operation, do not restrict it to only portrait or only landscape unless that orientation is essential. Test both orientations; convenience or a preferred mockup is not evidence of essentiality.
This is an original implementation summary, not replacement normative text. The sources below supply the precise requirement, its definitions and its qualifications.
