Header

The component for defining the top area of an article, chapter, or section.

Properties

role
string
(Required)

Always header for this component.

additions

An array of additions. This can be used to create a ComponentLink, allowing links to anywhere in News.

Adding a link to a Container component makes the entire component tappable. Any links used in its child components are not tappable.

anchor

An object that defines vertical alignment with another component.

animation
*

A object that defines an animation to be applied to the component.

The none value is used for conditional design elements. Adding it here has no effect.

behavior
*

An object that defines behavior for a component, like Parallax or Springy.

The none value is used for conditional design elements. Adding it here has no effect.

components

An array of components to display as child components. Child components are positioned and rendered relative to their parent component.

conditional
*

An instance or array of container properties that can be applied conditionally, and the conditions that cause them to be applied.

contentDisplay
*

An object that defines how to position child components within this container component. A HorizontalStackDisplay, for example, allows for displaying child components side by side.

On versions of News prior to iOS 11, child components are positioned as if contentDisplay were not defined.

The none value is used for conditional design elements. Adding it here has no effect.

hidden
boolean

A Boolean value that determines whether the component is hidden.

identifier
string

An optional unique identifier for this component. If used, this identifier must be unique across the entire document. You will need an identifier for your component if you want to anchor other components to it. See Anchor.

layout
*

An inline ComponentLayout object that contains layout information, or a string reference to a ComponentLayout object that is defined at the top level of the document.

If layout is not defined, size and position are be based on various factors, such as the device type, the length of the content, and the role of this component.

style
*

An inline ComponentStyle object that defines the appearance of this component, or a string reference to a ComponentStyle object that is defined at the top level of the document.

The none value is used for conditional design elements. Adding it here has no effect.

Discussion

A header is a structural component used to define the top area of an article or the top part of a Section or Chapter component. A header can contain child components—such as a Title or Heading—and is often used to layer titles and headings over a background image. (You specify the image in the style property with an ImageFill style.) The minimum size of a header component is determined by the size of its child components.

Example

{ "components": [ { "role": "header", "components": [ { "role": "title", "text": "Article Title", "style": { "fill": { "type": "image", "URL": "bundle://header.jpg", "fillMode": "cover", "verticalAlignment": "top", "horizontalAlignment": "center" } } } ] } ]}
