Styled System for the css prop

npm i @class101/styled-system__css

Styled System CSS lets you write style objects with responsive, theme-aware Styled System shortcuts.

// usage with the css prop
import React from 'react'
import css from '@class101/styled-system__css'

const Beep = props =>
  <div
    {...props}
    css={css({
      fontSize: [4, 5, 6],
      color: 'primary',
    })}
  />

// usage with a styled HOC
import styled from '@emotion/styled'
import css from '@class101/styled-system__css'

const Boop = styled('div')(
  css({
    fontSize: [ 4, 5, 6 ],
    color: 'primary',
    bg: 'gray',
    '&:hover': {
      color: 'secondary',
    },
  })
)

To make the css prop work with styled-components, babel-plugin-styled-components must be enabled.

Theme Keys

The following keys in your style object will work the same as Styled System props, pulling values from your theme object.

Responsive Arrays

All CSS properties accept arrays as values for responsive styles.

<div
  css={css({
    fontSize: [ 4, 5, 6 ],
  })}
/>

In this example, fontSize accepts an array, picking up values from the theme.fontSizes scale, and borderBottom is passed through as plain CSS.

<div
  css={css({
    // Styled System key
    fontSize: [ 3, 4, 5 ],
    // CSS property
    borderBottom: '2px solid tomato',
  })}
/>
