							|  |  | 
 | 
						
						
						
							|  |  | ## Usage
 | 
						
						
						
							|  |  | 
 | 
						
						
						
							|  |  | ```jsx
 | 
						
						
						
							|  |  | // 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.
 | 
						
						
						
							|  |  | 
 | 
						
						
						
							|  |  | ```jsx
 | 
						
						
						
							|  |  | // 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='gray.0' />
 | 
						
						
						
							|  |  | 
 | 
						
						
						
							|  |  | // background color
 | 
						
						
						
							|  |  | <Box bg='tomato' />
 | 
						
						
						
							|  |  | ```
 | 
						
						
						
							|  |  | 
 | 
						
						
						
							|  |  | ## Responsive Style Props
 | 
						
						
						
							|  |  | 
 | 
						
						
						
							|  |  | Set responsive width, margin, padding, font-size, and other properties with a shorthand array syntax.

 | 
						
						
						
							|  |  | <Box fontSize={[ 2, 3, 4 ]} />
 | 
						
						
						
							|  |  | 
 | 
						
						
						
							|  |  | // responsive margin
 | 
						
						
						
							|  |  | <Box m={[ 1, 2, 3 ]} />
 | 
						
						
						
							|  |  | 
 | 
						
						
						
							|  |  | // responsive padding
 | 
						
						
						
							|  |  | <Box p={[ 1, 2, 3 ]} />
