## 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.
