Question

css

I have configured all sac files to be compiled into one style file, but when creating 2 sac files, changes in the style file are replaced and should be added.

Answer 1

We take, make as many sas files as you need, create 1 more, the main one (main.sass) and import all those sas files into it and include main.css in html

Answer 2

As an option, make one css that imports everything.
But in general, there are assemblers for this - webpack and others
