Hello guys, I'm getting a bit flustered when it comes to refactoring my sass sheets. I'm kind of confused on when to use sass variables, as my understanding of a variable (or even functions) is DRY -- so if you use a value more than once, put it in a variable. But when I have things like mixins, or inheritance, I feel like the line becomes a little blurred and I'm feeling like my stylesheets are becoming a mess. Right now, I have it so that anytime I would use a variable twice (even if it's in a mixin, since I'm using a mixin multiple times for multiple components), I put it in a variable. But if I only use a value once, I'll put it in its respective component sheet. I'm curious to hear what your philosophies are.
