Table of Contents


// Example uses styled-components, but styled-system works with most other css-in-js libraries as well
import styled from 'styled-components'
import { space, layout, typography, color } from 'styled-system'

// Add styled-system functions to your component const Box = styled.div ${space} ${layout} ${typography} ${color}

Each style function exposes its own set of component props that handle styles based on values defined in a theme.

// width: 50%

// font-size: 20px (theme.fontSizes[4])

// margin: 16px ([2])

// padding: 32px ([3])

// color

// color: #333 (theme.colors.gray[0])

// background color
