CSS Architecture
5 min read
CSS architecture options: BEM for naming, ITCSS for layering, utility-first for composition, and CSS Modules for automatic scoping in React. Consistency within your team matters more than which method you pick.
CSS Architecture Strategies
- BEM — Block, Element, Modifier (naming convention)
- ITCSS — Inverted Triangle (layers by specificity)
- SMACSS — Scalable Modular Architecture
- Atomic CSS / Tailwind — utility-first classes
- CSS-in-JS — styled-components, Emotion
- CSS Modules — scoped class names in React/Vue
Choose one and apply it consistently across your project.
