Container

Containers are used to constrain a content's width to the current breakpoint, while keeping it fluid.

Props#

Container composes Box so you can pass all Box related props in addition to this.

The Container component is a single part component. All of the styling is applied directly to the div element.

To learn more about styling single part components, visit the Component Style page.

Theming properties#

The properties that affect the theming of the Container component are:

variant: The visual variant of the component. Variants for this component are not implemented in the default theme.
colorScheme: The color scheme of the component. Color schemes for this component are not implemented in the default theme.
size: The size of the component. Sizes for this component are not implemented in the default theme.

Theming utilities#

defineStyle: a function used to create style objects.
defineStyleConfig: a function used to define the style configuration for a single part component.

import { defineStyle, defineStyleConfig } from '@chakra-ui/react'

Customizing the default theme#

import { defineStyle, defineStyleConfig } from '@chakra-ui/react'

// define the base component styles
const baseStyle = {
  borderRadius: 'xl', // add a border radius
  fontWeight: 'medium', // change the font weight
}

// export the component theme
export const containerTheme = defineStyleConfig({ baseStyle })

After customizing the default theme, we can import it in our theme file and add it in the components property.

import { extendTheme } from '@chakra-ui/react'
import { containerTheme } from './components/Container'

const theme = extendTheme({
  components: {
    Container: containerTheme,
  },
})

export default theme

This is a crucial step to make sure that any changes that we make to the container theme are applied.

Adding a custom size#

Let's assume we want to create a small, medium, and large size. For demonstration, we will use a couple of different methods to define the max width. Here's how we can do that:

import { defineStyle, defineStyleConfig } from '@chakra-ui/react'

// define custom sizes
const sizes = {
  sm: defineStyle({
    maxW: '45ch',
    p: '4',
  }),
  md: defineStyle({
    maxW: 'container.sm',
    p: '6',
    fontSize: 'lg',
  }),
  lg: defineStyle({
    maxW: '75ch',
    p: '8',
    fontSize: 'xl',
  }),
}

// export the component theme
export const containerTheme = defineStyleConfig({ sizes })

Every time you're adding anything new to the theme, you need to run the CLI command to get proper autocomplete in your IDE. You can learn more about the CLI tool here.

Adding a custom variant#

Let's assume we want to include a couple of variants: one that can use a color scheme and a bold one that is black and white. Here's how we can do that:

import { defineStyle, defineStyleConfig } from '@chakra-ui/react'

// define styles for custom variant
const colorfulVariant = defineStyle((props) => {
  const { colorScheme: c } = props // add color scheme as a prop
  return {
    _light: {
      bg: `${c}.200`,
      color: `${c}.800`,
    },
    _dark: {
      bg: `${c}.700`,
      color: `${c}.200`,
    },
  }
})

const boldVariant = defineStyle((props) => {
  return {
    borderRadius: 'none',
    border: '2px solid',
    fontFamily: 'mono',
    _light: {
      bg: 'white',
      color: `black`,
    },
    _dark: {
      bg: 'black',
      color: 'white',
    },
  }
})

// define custom variants
const variants = {
  colorful: colorfulVariant,
  bold: boldVariant,
}

// export the component theme
export const containerTheme = defineStyleConfig({ variants })

Using a custom color scheme#

Let's assume we want to use our own custom color scale based on our brand. First, we need to define the color scale in the main theme file:

import { extendTheme } from '@chakra-ui/react';
import { containerTheme } from './components/Container';

const theme = extendTheme({
  // add a custom color scheme
  colors: {
    brand: {
      50: '#dafff3',
      ...
      500: '#13e4b1',
      ...
      900: '#001b0e',
    },
  },

});

export default theme;

Then, we can use the custom color scale as the color scheme for the container:

<Container colorPalette='brand'>...</Container>

Changing the default properties#

Let's assume we want to add a default size, variant, and color scheme of every container in our app. Here's how we can do that:

import { defineStyle, defineStyleConfig } from '@chakra-ui/react'

// define which sizes, variants, and color schemes are applied by default
const defaultProps = {
  size: 'md',
  variant: 'colorful',
  colorScheme: 'brand',
}

// export the component theme
export const containerTheme = defineStyleConfig({ defaultProps })

Showcase#

import React from 'react';
import { ChakraProvider, Box, Container, VStack } from '@chakra-ui/react';
import theme from './theme';
import { ColorModeSwitcher } from './ColorModeSwitcher';

export default function App() {
  return (
    <ChakraProvider theme={theme}>
      <Box position="relative" h="100vh" p={4}>
        <VStack>
          <Container>
            This container has the new theme default properties applied of
            medium size, brand color scheme, and colorful variant.
          </Container>
          <Container size="sm" colorScheme="gray">
            This container has the small size, gray color scheme, and new
            default colorful variant applied.
          </Container>
          <Container size="lg" variant="bold">
            This container has the large size, no color scheme, and the bold
            variant applied.
          </Container>
          <Container size="sm" variant="bold">
            This container has the small size, no color scheme, and the bold
            variant applied.
          </Container>
          <Container size="lg" variant="colorful" colorScheme="blue">
            This container has the new default colorful variant with the large
            size and blue color scheme applied.
          </Container>
        </VStack>
        <ColorModeSwitcher position="fixed" bottom={3} left={3} />
      </Box>
    </ChakraProvider>
  );
}
