Global classes layout css only visibly on frontend

Hello Cwicly

I am not sure if this is a bug or just a feature that doesn’t exist yet, but to make my website responsive i add layout changes on different breakpoints than the standard ones. So i have to do this with global classes. The problem is that these changes don’t reflect in the builder. I’m not sure if this includes all css properties, but ive only use flexbox and css-grid.

Thanks in advance and a happy new year,
Niek.
