Content does not restrict its view and operation to a single display orientation, such as portrait or landscape, unless a specific display orientation is essential.
Examples where a particular display orientation may be essential are a bank check, a piano application, slides for a projector or television, or virtual reality content where binary display orientation is not applicable.
Testing & RemediationHow to test: If you are on a mobile device, flip the view from portrait to landscape. Ensure that all content adapts to the different viewport and displays properly. If you are on a desktop or laptop, drag the corner of the browser and see if the content adapts properly to different window sizes. Some sites will need to be refreshed to see if this works properly (sites that are built on a dynamic serving template instead of a responsive template). How to remediate:
- Use CSS to set the orientation to allow both landscape and portrait.
- Use of show/hide controls to allow access to content in different orientations.
