Emotion vs Styled-Components vs Theme-UI vs Rebass: 架构选型与实战对比

Fast, expressive styling for React.
Server components, client components, streaming SSR, React Native—one API.

styled-components is largely maintained by one person. Please help fund the project for consistent long-term support and updates: Open Collective

Style React components with real CSS, scoped automatically and delivered only when needed. No class name juggling, no separate files, no build step required.

• Works everywhere React runs. Server components, client components, streaming SSR, and React Native—same API, automatic runtime detection.
• Full CSS, no compromises. Media queries, pseudo-selectors, nesting, keyframes, global styles. If CSS supports it, so does styled-components.
• TypeScript-first. Built-in types ship with the package. Props flow through to your styles with full inference—no @types install, no manual generics.
• <13kB gzipped. Small enough to disappear in your bundle. No build plugin required.

Install

npm install styled-components

pnpm add styled-components

yarn add styled-components

Quick examples

Dynamic props

Vary styles based on component props. Prefix transient props with $ to keep them off the DOM.

import styled from 'styled-components';

const Button = styled.button<{ $primary?: boolean }>`
  background: ${props => (props.$primary ? 'palevioletred' : 'white')};
  color: ${props => (props.$primary ? 'white' : 'palevioletred')};
  font-size: 1em;
  padding: 0.25em 1em;
  border: 2px solid palevioletred;
  border-radius: 3px;
`;

<Button>Normal</Button>
<Button $primary>Primary</Button>

Extending styles

Build variants on top of existing styled components.

const TomatoButton = styled(Button)`
  background: tomato;
  color: white;
  border-color: tomato;
`;

Polymorphic as prop

Swap the rendered element without changing styles.

// Renders a <a> tag with Button styles
<Button as="a" href="/home">Link Button</Button>

Pseudos and nesting

Use & to reference the component's generated class name—works with pseudo-classes, pseudo-elements, and nested selectors.

const Input = styled.input`
  border: 1px solid #ccc;
  border-radius: 4px;
  padding: 0.5em;

  &:focus {
    border-color: palevioletred;
    outline: none;
  }

  &::placeholder {
    color: #aaa;
  }
`;

Animations

Define @keyframes once, reference them across components. Names are scoped automatically.

import styled, { keyframes } from 'styled-components';

const rotate = keyframes`
  from { transform: rotate(0deg); }
  to { transform: rotate(360deg); }
`;

const Spinner = styled.div`
  animation: ${rotate} 1s linear infinite;
  width: 40px;
  height: 40px;
  border: 3px solid palevioletred;
  border-top-color: transparent;
  border-radius: 50%;
`;

Theming

Share design tokens across your app via React context. Every styled component receives props.theme.

import styled, { ThemeProvider } from 'styled-components';

const theme = {
  fg: 'palevioletred',
  bg: 'white',
};

const Card = styled.div`
  background: ${props => props.theme.bg};
  color: ${props => props.theme.fg};
  padding: 2em;
`;

<ThemeProvider theme={theme}>
  <Card>Themed content</Card>
</ThemeProvider>

RSC-compatible themes

createTheme turns your tokens into CSS custom properties. Class name hashes stay stable across theme variants—no hydration mismatch when switching light/dark.

import styled, { createTheme, ThemeProvider } from 'styled-components';

const { theme, GlobalStyle: ThemeVars } = createTheme({
  colors: {
    fg: 'palevioletred',
    bg: 'white',
  },
  space: {
    md: '1rem',
  },
});

const Card = styled.div`
  color: ${theme.colors.fg};       /* var(--sc-colors-fg, palevioletred) */
  background: ${theme.colors.bg};
  padding: ${theme.space.md};
`;

// Render <ThemeVars /> at the root to emit the CSS variable declarations
// Pass the theme to ThemeProvider for stable hashes
<ThemeProvider theme={theme}>
  <ThemeVars />
  <Card>Token-driven content</Card>
</ThemeProvider>

Shared styles with css

Extract reusable style blocks to share across components or apply conditionally.

import styled, { css } from 'styled-components';

const truncate = css`
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
`;

const Label = styled.span`
  ${truncate}
  max-width: 200px;
`;

Styling third-party components

Wrap any component that accepts a className prop.

import styled from 'styled-components';
import { Link } from 'react-router-dom';

const StyledLink = styled(Link)`
  color: palevioletred;
  text-decoration: none;

  &:hover {
    text-decoration: underline;
  }
`;

Global styles

Inject app-wide CSS like resets and font faces. Supports theming and dynamic updates.

import { createGlobalStyle } from 'styled-components';

const GlobalStyle = createGlobalStyle`
  body {
    margin: 0;
    font-family: system-ui, sans-serif;
  }
`;

// Render <GlobalStyle /> at the root of your app

Attrs

Set default or static HTML attributes so consumers don't have to.

const PasswordInput = styled.input.attrs({
  type: 'password',
  placeholder: 'Enter password',
})`
  border: 1px solid #ccc;
  padding: 0.5em;
`;
