NO BUG: Dynamic variables can't be imported

Hello,

I was trying to use a custom code I found from repository and I discovered that I can’t import variables that has values for light & darkmode.

for example,
:root{
–base-color: white;
–base-variant: #e8e9ed;
–text-color: #111528;
–secondary-text: #232738;
–primary-color: #3a435d;
–accent-color: #0071ff;
}

.darkmode{
–base-color: #070b1d;
–base-variant: #101425;
–text-color: #ffffff;
–secondary-text: #a4a5b8;
–primary-color: #3a435d;
–accent-color: #0071ff;
}

how do I import these variables while storing the values of the darkmode class?

I feel it’s either a missing feature/bug when I pasted in the variable import screen to import the codes
