"If you make websites/apps with React check out Styled System if you haven't already. You will be amazed at how much faster you can build."

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, 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%
<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' />
