Design system utilities for styled-components, glamorous, and other css-in-js libraries
Styled System is a utility for creating consistent, responsive, and theme-based design systems in React. It provides a set of functions and utilities to style components using a system of design tokens, such as spacing, colors, and typography, making it easier to build UI components that adhere to a design system.
Responsive Styles
Styled System allows you to define responsive styles using arrays. The `p` prop sets padding, `bg` sets background color, and `width` sets the width of the component. The values in the arrays correspond to different breakpoints.
const Box = styled.div`
${space}
${color}
${layout}
`;
<Box p={[1, 2, 3]} bg={['red', 'green', 'blue']} width={[1, 1/2, 1/4]} />Theme-based Design
Styled System integrates with a theme object to provide consistent styling across your application. The `color` and `space` utilities use the theme to apply styles.
const theme = {
colors: {
primary: 'blue',
secondary: 'green',
},
space: [0, 4, 8, 16, 32],
};
const Box = styled.div`
${color}
${space}
`;
<Box color='primary' p={2} />Utility Functions
Styled System provides utility functions like `space`, `color`, and `layout` that can be used to style components. These functions map props to CSS properties based on the theme.
import { space, color, layout } from 'styled-system';
const Box = styled.div`
${space}
${color}
${layout}
`;
<Box m={2} p={3} bg='primary' width={1/2} />Emotion is a library designed for writing CSS styles with JavaScript. It provides powerful and flexible styling capabilities, including support for theming and responsive styles. Compared to Styled System, Emotion offers more granular control over CSS but requires more manual setup for design systems.
Styled-components is a library for styling React components using tagged template literals. It allows for writing actual CSS to style components and supports theming and dynamic styling. While it doesn't provide the same utility functions as Styled System, it can be used in conjunction with Styled System for a more comprehensive solution.
Tailwind CSS is a utility-first CSS framework that provides low-level utility classes for building custom designs. It offers a different approach compared to Styled System by using predefined classes instead of JavaScript functions. Tailwind CSS is highly customizable and can be used to create responsive and theme-based designs.

npm i styled-system
"This is honestly my favourite way to build UI components right now
"

Try the examples on CodeSandbox
// Example uses styled-components, but styled-system works with most other css-in-js libraries as well
import styled from 'styled-components'
import { space, width, fontSize, color } from 'styled-system'
// Add styled-system functions to your component
const Box = styled.div`
${space}
${width}
${fontSize}
${color}
`
Each style function exposes its own set of component props that handle styles based on values defined in a theme.
// width: 50%
<Box width={1/2} />
// font-size: 20px (theme.fontSizes[4])
<Box fontSize={4} />
// margin: 16px (theme.space[2])
<Box m={2} />
// padding: 32px (theme.space[3])
<Box p={3} />
// color
<Box color='tomato' />
// color: #333 (theme.colors.gray[0])
<Box color='grays.0' />
// background color
<Box bg='tomato' />
