I have a button in perspective which contains a text and an image. The problem is that when I resize the emebedded view, the button itself shrinks but the image and the text do not shrink. I attach an screenshot of the configuration for the button
For the text, use CSS calc() for this. Put it in the textStyle of the label as fonSize.
calc(0.25*(1vh + 1vw))
vh = view Height
vw = view Width
I'm not sure if this will work on the image though.
