Apologies if the following doesn't make sense, I'm still trying to learn how scss and css works.
Lets say I have 2 developers.
Developer 1 manually adds bits to the css file. Developer 2 picks up the project and uses scss to add bits to the css file. Would Developer 1's work disappear? I'm guessing that when Developer 2 compiles the css file it overwrites anything which is not in the scss file?
Again, apologies if this doesn't make sense.
I just tested it. And the changes i made to the css file got overwritten when i compiled my scss. So yes, compiling your scss file overwrites the changes to css.
