Thank for your response kgamble!
I have tried all of yours advice:
i can’t switch to Flex because my pages layout use different shapes, and i cannot configurate them on a flex container.
The Style class with media query is not working because i need to change live the value of the font, and not to change it at prefixed values.
I tried to change the font size value to em, but that is not resizing. It stays exactly like is it.
My goal is to maintain the label/component proportion: with this logic i expected that the text highlighted in yellow won’t exceed it’s space, and the text inside the orange label would shrink to stay inside the label without disappear, but it’s not working.
Is there a built in feature?
