modular-css

Supports composing styles from multiple classes into one, reducing CSS duplication, as shown in the composition feature example in the README.

Allows defining reusable constants with @value for colors and sizes, enabling consistent theming across stylesheets, demonstrated in the values section.

Automatically generates unique class names to prevent style collisions, with opt-out via :global() for flexibility, as highlighted in the selector scoping feature.

Integrates with Rollup, Vite, Webpack, CLI, and more, offering flexibility in setup without locking into a specific ecosystem, per the tool agnostic feature.
