Content must not be lost, blocked, or overlapped when the device’s orientation is changing.

Who might be affected


When content is obscured, covered, or unavailable when changing the screen orientation, this creates a bad experience for all users. However, this content becomes wholly inaccessible and unusable for users of assistive technologies that support only a specific orientation or for users who cannot change their device's orientation. Therefore, ensuring that the entire content is available and operable both in portrait and landscape orientations is essential.

How Users Are Affected

Users of assistive technologies which support only a specific screen orientation may not be able to perceive the content or use the app.
