How to know which styles change at breakpoints?

Hi - Is there an easy way to tell which styles have changes at breakpoints? Or put another way, I’d like to quickly know which styles differ by breakpoint.

Context: I’m trying to understand how the template I’m using behaves at different breakpoints (and to perhaps simplify). I can do some of this visually, but not all of it (since I’m not using all styles).

I can and have looked at the exported CSS, but my intuition is that there must be a better way.

Thanks for your help,
