Is it possible to style REF element in sequence diagram?

Question

Answer 1

The documentation is not up to date...

Sorry about that.

You can have:

@startuml
skinparam sequenceReferenceBorderColor red
skinparam sequenceReferenceBackgroundColor yellow
skinparam sequenceReferenceHeaderBackgroundColor blue

Dummy -> Alice : foo1
ref over Alice, Bob : this is a reference over Alice and Bob
ref#7700FF over Alice, Other, Bob : this is a reference over Alice and Other

Other --> Alice : ok again

@enduml

Hope this helps!

Answer 2

Hello all,

How to use different style for different ref element?

Now (from 1.2019.9++) with new style functionality, we can change style during sequence as:

@startuml
<style>
  sequenceDiagram {
    reference {
      LineColor red
      BackGroundColor yellow
      LineThickness 2.0
    }
    referenceHeader {
      LineColor red
      BackGroundColor blue
      FontStyle bold
    }
}
</style>
Dummy -> Alice : foo1
ref over Alice, Bob : this is a reference over Alice and Bob
ref#7700FF over Alice, Other, Bob : this is a reference over Alice and Other

Other --> Alice : ok again
Alice -> Bob : new style
<style>
  sequenceDiagram {
    reference {
      LineColor blue
      BackGroundColor palegreen
    }
    referenceHeader {
      LineColor blue
      BackGroundColor green
      FontColor white
    }
}
</style>
ref over Alice, Bob : this is another1 reference over Alice and Bob

Alice <- Bob : another new style
<style>
  sequenceDiagram {
    reference {
      LineColor red
      BackGroundColor pink
    }
    referenceHeader {
      LineColor red
      BackGroundColor blue
    }
}
</style>
ref over Alice, Bob : this is another2 reference over Alice and Bob
