rscss
Reasonable System for CSS Stylesheet Structure
...It proposes a consistent vocabulary—components, elements, variants, and utilities—so teams can infer intent directly from class names. The approach is intentionally lightweight: it’s a set of conventions, not a framework, so it layers cleanly over any build system or preprocessor. By nudging you toward small, independent components with clear boundaries, rscss reduces selector specificity battles and cascade surprises. The guidelines cover folder structure, naming, and how to scope modifiers, which helps reduce churn when multiple contributors touch the same UI. Even if your team eventually adopts a utility framework or CSS-in-JS, rscss is a helpful reference for reasoning about class semantics and keeping styles tidy.
