Do you use Sass with CSS Modules? I've found it to be an excellent pairing. I put shared styles/variables (like colours) in top-level Sass partials that individual component styles can import if they need them.

The only part I dislike about CSS Modules is having to use camelCased class names, or string references (styles['class-name']), which always feel awkward. I prefer kebab-case for CSS because it's a lot more flexible (more word separators: "-", "--", "_", "__", etc.), but I'm sure I'll adapt.

Agree with this smaller pain point in the vast peace of mind that CSS Modules bring.

I try to simplify as much as possible to a single word and repeat them a lot since there’s no collision, so you can usually expect a .container, .items, .item in most components, all top level but SASS helping with other annoyances like pseudo selectors, parents and nesting where it makes sense.

You just have to remind yourself that you aren’t writing css class names, even though it looks like css class names you’re picking js identifiers. Once I made peace with that it got a lot easier to write camelCase class names- and even switch back to kebab-case when necessary.
