StyleC

A composite style. Two more or more styles that must be applied as a whole in order to be successful.

This demands that anyone using this style:

1. Obtain an instance of all sub-styles.

2. Acknowledge the purpose of each sub-style (and thus not accept them in the wrong order and apply them to the wrong targets).

Before styles can be composed, they must be annotated with a name. Do so like avatarStyle.named('avatar). Named styles can then be composed using :*:.

val profileStyle: StyleC =
  titleStyle.named('title) :*: avatarStyle.named('avatar) :*: buttonStyle.named('btn)
