CSS Blocks is a component-oriented CSS authoring system from LinkedIn that compiles to highly optimized stylesheets using build-time static analysis of templates. It provides scoped styles, one CSS file per component, object-oriented block inheritance, and project-wide dead code elimination with a tiny runtime.

Use cases

• write scoped component styles for a design system
• optimize CSS by eliminating unused styles at build time
• catch CSS errors at build time instead of runtime
• compose styles across components with inheritance
• reduce stylesheet size for a large web app

When to choose

• building a design system or component library with maintainable scoped CSS
• you want statically analyzable styles with build-time error checking
• stylesheet performance and dead code elimination are priorities

When to avoid

• you need a modern actively maintained tool - development has stalled since 2023
• your stack uses frameworks without CSS Blocks integrations
• you prefer runtime CSS-in-JS or utility-first approaches
