SupportedUnits

You can define units for setting dimensions in Apple News Format. Values without a unit definition are interpreted in points (pt).

The following are the supported units in Apple News Format:

• vw. Defines a size or margin based on the viewport width.

• vh. Defines a size or margin based on the viewport height.

• vmin. Defines a size or margin based on the shortest side of the viewport (height or width, whichever is shorter).

• vmax. Defines a size or margin based on the longest side of the viewport (height or width, whichever is longer).

• dg. Defines a size or margin based on the document gutter. See Layout.

• dm. Defines a size or margin based on the document margin. See Layout.

• cw. Defines a size based on the component’s width. Note that this unit can only be used for sizing the component itself.

• pw. Defines the component width based on the parent component width.

• pt. Defines a unit of measure in points (the default).
