Creating an Adaptive Header in Axure 9

Hello–I am trying to create a simple Master Header (one image and two text blocks) that I can then use for default Portrait Phone/Tablet/Large Display sizes.

I saw this thread from 2018 that is now closed, but honestly can’t really make sense of it.

Any advice on setting up a Master with an adaptive view so I can simply create it once and apply? Thank you.

Regards,
Dina
