Failure due to locking the orientation to landscape or portrait view

Important Information about Techniques

See Understanding Techniques for WCAG Success Criteria for important information about the usage of these informative techniques and how they relate to the normative WCAG 2.1 success criteria. The Applicability section explains the scope of the technique, and the presence of techniques for a specific technology does not imply that the technology can be used in all situations to create content that meets WCAG 2.1.

Applicability

This technique relates to Success Criterion 1.3.4: Orientation (Failure).

Description

The objective of this technique is to describe how restricting the view of content to a single orientation is a failure to allow content to be viewed in multiple orientations. When content is presented with a restriction to a specific orientation, users must orient their devices to view the content in the orientation that the author imposed. Some users have their devices mounted in a fixed orientation (e.g. on the arm of a power wheelchair), and if the content cannot be viewed in that orientation it creates problems for the user.

If a specific orientation is determined to be essential for the operation and viewing of the content, then this failure technique will not apply.

Examples

Tests

Procedure

  1. Open the content in landscape view. Check that the content is oriented for this view.
  2. Open the content in portrait view. Check that the content is oriented for this view.
  3. Check if portrait or landscape view is essential for the viewing and operation of the content.
  4. If there are any controls in the content, user agent, operating system, or device that restrict or allow orientation changes, check that the controls can be set to allow checks one and two to be true.

Expected Results

  • If check #1 or check #2 is false, and checks #3 and #4 are false, then this failure condition applies and content fails the Success Criterion.
