    Grid Styletr

    Responsive React grid system built with styletron-react

    A fork of grid-styled: "same" API but for styletron-react

    Getting Started

    npm i grid-styletr
    import React from 'react'
    import { Flex, Box } from 'grid-styletr'
    const App = () => (
        <Box width={1/2} px={2}>
          Half width
        <Box width={1/2} px={2}>
          Half width
    // Different widths at different breakpoints
    // Fixed pixel width
    <Box width={256} />
    // CSS value width
    <Box width='40em' />
    // Padding
    <Box p={2} />
    // Padding top
    <Box pt={2} />
    // Padding bottom
    <Box pb={2} />
    // Padding left
    <Box pl={2} />
    // Padding right
    <Box pr={2} />
    // x-axis padding (left and right)
    <Box px={2} />
    // y-axis padding (top and bottom)
    <Box py={2} />
    // Margin
    <Box m={2} />
    // Margin top
    <Box mt={2} />
    // Margin bottom
    <Box mb={2} />
    // Margin left
    <Box ml={2} />
    // Margin right
    <Box mr={2} />
    // x-axis margin (left and right)
    <Box mx={2} />
    // y-axis margin (top and bottom)
    <Box my={2} />
    // margin auto
    <Box m='auto' />
    // negative margins
    <Box mx={-2} />
    // Display inline-block grid
    import { Grid } from 'grid-styletr'
      <Grid width={1/2}>Half</Grid>
      <Grid width={1/2}>Half</Grid>

    <Box />

    The Box component handles width, margin and padding.


    width (number|string|array)

    Sets width, where numbers 0-1 are percentage values, larger numbers are pixel values, and strings are raw CSS values with units. Pass an array to set different widths at different breakpoints for responsive styles.

    Margin and Padding Props

    Both margin and padding props accept numbers, strings, and arrays as values. Using a number from 0-4 will reference a step on the spacing scale. Larger numbers are converted to pixel values. Negative Numbers can be used to set negative margins and compensate for grid gutters. Strings are passed directly for other valid CSS values.

    Use array values to set different margin or padding values per breakpoint for responsive styles.

    Margin and padding props follow a shorthand syntax for specifying direction.

    • m: margin
    • mt: margin-top
    • mr: margin-right
    • mb: margin-bottom
    • ml: margin-left
    • mx: margin-left and margin-right
    • my: margin-top and margin-bottom
    • p: padding
    • pt: padding-top
    • pr: padding-right
    • pb: padding-bottom
    • pl: padding-left
    • px: padding-left and padding-right
    • py: padding-top and padding-bottom

    flex (string|array)

    Sets the flex property.

    <Box flex='1 1 auto' />

    order (number|string|array)

    Sets the order property.

    <Box order={2} />

    is (Component|string)

    Sets the underlying HTML element.

    <Box is='section' />

    <Flex />

    The Flex component extends the Box component and sets display flex. It also includes the following props:

    • align (string|array) sets align-items
    • justify (string|array) sets justify-content
    • direction (string|array) sets flex-direction
    • wrap (boolean|array) sets flex-wrap: wrap
    • column (boolean) shortcut for flex-direction: column

    <Grid />

    The Grid component extends the Box component and sets display inline-block for an alternative to flexbox layout.

    Responsive Styles

    Most props accept arrays as values for mobile-first responsive styles, where the first value is for all breakpoints, then each value after is for a min-width media query from that breakpoint and up. The Box component uses styled-system for these props.

    // 100% below the smallest breakpoint,
    // 50% from the next breakpoint and up,
    // and 25% from the next breakpoint and up
    <Box w={[ 1, 1/2, 1/4 ]} />
    // responsive margin
    <Box m={[ 1, 2, 3, 4 ]} />
    // responsive padding
    <Box p={[ 1, 2, 3, 4 ]} />

    Extending Components

    Using styletron-react, you can customize any of the grid-styletr components' styles.


    // Example
    import { styled } from 'styletron-react'
    import { Flex } from 'grid-styletr'
    const InlineFlex = styled(Flex, {
      display: 'inline-flex'

    Max-Width Container

    // Example
    import { styled } from 'styletron-react'
    import { Box } from 'grid-styletr'
    const Container = styled(Box, {
      maxWidth: '1024px',
      marginLeft: 'auto',
      marginRight: 'auto',

    Auto Grid

    Components can also be extended with React. This example creates components for a grid with set gutters where the columns expand to fill in the space.

    // Example
    import React from 'react'
    import { Flex, Box } from 'grid-styletr'
    const Row = props => (
    const Column = props => (
        flex='1 1 auto'


    Grid Styletr uses smart defaults, but to customize the values, use ThemeProvider component.

    import React from 'react'
    import { ThemeProvider } from 'grid-styletr'
    const App = () => (
          space: [ 0, 6, 12, 18, 24 ],
          breakpoints: [ 32, 48, 64 ]
          <Grid>Grid with custom spacing scale and breakpoints</Grid>


    The Grid component uses a mobile-first responsive approach, where any value set works from that breakpoint and wider. Breakpoints are hard-coded to the following min-widths: 40em, 52em, 64em.

    To customize, provide an array of numbers that will be converted to ems.

    Spacing Scale

    Grid Styletr components' margin and padding props use a 4 step spacing scale to help keep things aligned and keep layouts consistent.

    The default scale is based on an 8px/powers-of-two grid: [ 0, 8, 16, 32, 64 ], which helps keep spacing consistent and elements aligned even when nesting components.
