Styled Components Library

Styled Components is a CSS-in-JS library for React created by Max Stoiber, Glen Maddern, Phil Plückthun, and Evan Jacobs in 2016, providing a component-based styling approach where styles are co-located with their components as tagged template literals, with features including automatic vendor prefixing, critical CSS extraction for server-side rendering, theming through context providers, prop-based dynamic styling, component composition through the as and forwardedAs props, extended styles through inheritance, global styles through the createGlobalStyle function, keyframe animations, and ref forwarding, adopted by companies including Coinbase, Vogue, Bloomberg, Target, InVision, and over thirty thousand other companies for their styling infrastructure. The styled factory creates styled React components from HTML elements or existing components, with the template literal containing CSS rules that are scoped to the component through automatically generated unique class names, eliminating class name collisions and dead CSS, while JavaScript interpolation in the template literal enables dynamic styling based on component props, with the interpolated values re-evaluated on every render for real-time style updates. The theming system provides a ThemeProvider component that passes theme data through React context, with the theme accessible through props in every styled component, enabling consistent design tokens including colors, spacing, typography, breakpoints, and z-index values across the entire application. The server-side rendering extracts critical CSS by rendering the component tree to a style sheet that is injected into the HTML response. The performance through the stylis CSS preprocessor. The babel plugin for minification and dead code elimination. The TypeScript support. The React Native support. The component inheritance. Designed by Max Stoiber. Designed for React developers.
