I actually take it one step further and have classes such as `border-1-px border-dark border-bottom standard-margin no-margin-top`. Seem weird at first but combined with flexbox (if your target is the evergreens) you never overwrite and you got one stylesheet for pretty much all of your projects. It's a real production boost. Really not a fan of CSS-in-JS. I like to keep my components JS+JSX only.
