• Alternate dimensions

Getting Started

npm install @infotech/reflexbox

import React from 'react'
import { Box } from '@infotech/reflexbox'

class Component extends React.Component {
  render() {
    return (
      <Box flex>
        <Box px={2} w={1/2}>Box A</Box>
        <Box px={2} w={1/2}>Box B</Box>
      </Box>
    )
  }
}

Usage

// Fractional width
<Box w={1/2} />

// Pixel width
<Box w={128} />

// Responsive widths
<Box w={[ 1, 1/2, 1/4 ]} />

// Special units
<Box w="1md" />

// Padding
<Box p={2} />

// Responsive padding
<Box p={[ 1, 2, 3 ]} />

// Margin
<Box m={2} />

// Responsive margin
<Box m={[ 1, 2, 3 ]} />

// top, right, bottom, left
<Box
  mt={1}
  mr={2}
  mb={3}
  ml={2}
/>

// x-axis
<Box mx={-2} />

// y-axis
<Box my={3} />

// min/max width, min/max-height
<Box
  minw="1ui"
  maxw="2bl"
  minh="1md"
  maxw="5bl"
/>

// align-items: center
<Flex align='center' />

// justify-content: space-between
<Flex justify='space-between' />

// Flex wrap

API

<Box />

Primitive for controlling width, height, margin, padding and more.

Props

Both <Flex /> and <Box /> share the same props.

• w (number|array|string) sets width, where numbers 0-1 are percentage values, larger numbers are pixel values, and strings are raw CSS values with units.
• h (number|array|string) sets height in the same way as width
• minw (number|array|string) sets min-width
• maxw (number|array|string) sets max-width
• minh (number|array|string) sets min-height
• maxh (number|array|string) sets max-height
• flex (boolean) sets display: flex
• wrap (boolean) sets flex-wrap: wrap
• column (boolean) sets flex-direction: column
• auto (boolean) sets flex: 1 1 auto
• order (number) sets order
• align (string) sets align-items
• justify (string) sets justify-content

Margin and Padding

Margin and padding props accept numbers 0-4 for values from the spacing scale [ 0, 8, 16, 32, 64 ]. Numbers greater than 4 will be used as pixel values. Negative values can be used for negative margins. Strings can be passed for special units, and other CSS values, e.g. mx='auto'

• m (number|string) margin based on a scale from 0–4.
• mx (number|string) x-axis margin based on a scale from 0–4.
• my (number|string) y-axis margin based on a scale from 0–4.
• mt (number|string) margin-top based on a scale from 0–4.
• mb (number|string) margin-bottom based on a scale from 0–4.
• ml (number|string) margin-left based on a scale from 0–4.
• mr (number|string) margin-right based on a scale from 0–4.
• p (number|string) padding based on a scale from 0–4.
• px (number|string) x-axis padding based on a scale from 0–4.
• py (number|string) y-axis padding based on a scale from 0–4.
• pt (number|string) padding-top based on a scale from 0–4.
• pb (number|string) padding-bottom based on a scale from 0–4.
• pl (number|string) padding-left based on a scale from 0–4.
• pr (number|string) padding-right based on a scale from 0–4.

Responsive Array Prop Values

All props accept arrays as values for mobile-first responsive styles.

// Set widths for different breakpoints, starting from smallest to largest
// This example will be 100% width below the smallest breakpoint,
// then 50% and 25% for the next two breakpoints respectively
<Box w={[ 1, 1/2, 1/4 ]} />

Null values can be passed to the array to skip a breakpoint.

<Box w={[ 1, null, 1/2 ]} />

Configuration

Values for the breakpoints and space scale can be configured with React Context.

Context can be set manually or with the <ReflexProvider /> component.

import React from 'react'
import { ReflexProvider, Flex, Box } from '@infotech/reflexbox'

const space = [ 0, 6, 12, 18, 24 ]
const breakpoints = [ 32, 48, 64 ]

class App extends React.Component {
  render () {
    return (
      <ReflexProvider
        space={space}
        breakpoints={breakpoints}>
        <Flex mx={-2}>
          <Box w={1/4} px={2}>Box</Box>
          <Box w={1/4} px={2}>Box</Box>
          <Box w={1/4} px={2}>Box</Box>
          <Box w={1/4} px={2}>Box</Box>
        </Flex>
      </ReflexProvider>
    )
  }
}

Higher Order Component

The core Reflexbox higher-order component can be used on any element that accepts className as a prop.

import React from 'react'
import { reflex } from '@infotech/reflexbox'
import MyInput from './MyInput'

const FlexInput = reflex(MyInput)

const App = () => (
  <div>
    <FlexInput
      w={1/2}
      mb={2}
      defaultValue='Flex Input'
    />
  </div>
)
