## What it is
goober is a less-than-1KB CSS-in-JS library with a styled-components-like API for React, Preact, and vanilla DOM. It supports styled components, theming, keyframes, and server-side CSS extraction while keeping bundle size minimal.

## Use cases
- style react components with css-in-js without a large bundle
- replace styled-components or emotion to reduce javascript bundle size
- extract critical css during server-side rendering
- theme components with shared colors and sizes
- use the styled pattern in preact apps
- write scoped css with keyframes and hover states in javascript

## When to choose
- bundle size is critical and you want css-in-js under 1KB
- you already like the styled-components API but not its footprint
- you need SSR with easy css extraction
- you use react or preact and want a drop-in styled alternative

## When to avoid
- you need the full ecosystem and advanced features of styled-components or emotion
- your team prefers plain css, css modules, or utility-first frameworks
- you rely on rarely used css-in-js features not supported by goober

- artifact type: library
- maturity: active
