## What it is
SUIT CSS is a collection of CSS packages and a PostCSS-based preprocessor implementing a component-based styling methodology for web UIs. It provides base styles, utilities, components, and a naming convention with tooling for CSS encapsulation testing.

## Use cases
- style react components with a consistent css methodology
- scope css for component-based web apps
- lint css for bem naming convention conformance
- build css with custom media queries and custom properties
- use modular css utility and component packages via npm

## When to choose
- building component-based web apps with React, Ember, or Angular that need scoped, predictable CSS
- you want a modular, npm-installable CSS utility and component system
- you need a future-facing CSS preprocessor with import inlining and autoprefixing

## When to avoid
- you prefer utility-first frameworks like Tailwind CSS
- you need a full-featured modern CSS-in-JS solution
- the project is in maintenance mode with infrequent releases
