# About Containers Learn the basic Apple News Format container concepts required for the three advanced tutorials. ## Discussion Most of the design and layout effects in this tutorial require you to create hierarchies of nested components. In Apple News Format JSON, a container is a component that can hold other components. Container components include four types: `chapter`, `header`, `section`, and `container`. This is an example of a simple container. ```json { "role": "container", "components": [ { "role": "title", "text": "A Photo", }, { "role": "photo", "URL": "bundle://.", } ] } ``` In the example above, the `container` component has two child components. Notice that a container has a property named `components` whose value is an array. Any components inside the container’s `components` array are children of the container. ## See Also [`object Container`](/documentation/AppleNewsFormat/Container) Properties shared by all container types. --- Copyright © 2026 Apple Inc.
