Default Theme

The theme object is where you define your application's color palette, type scale, font stacks, breakpoints, border radius values, and more.

Theming with Chakra UI is based on the Styled System Theme Specification

Colors#

Add a theme.colors object to provide colors for your project. By default these colors can be referenced by the color, borderColor, backgroundColor, fill, stroke, styles.

We recommend adding a palette that ranges from 50 to 900. Tools like Themera, Smart Swatch, Coolors or Palx are available to generate these palettes.

// theme.js
export default {
  colors: {
    transparent: 'transparent',
    black: '#000',
    white: '#fff',
    gray: {
      50: '#f7fafc',
      // ...
      900: '#171923',
    },
    // ...
  },
}

Chakra provides a sensible default theme inspired by Tailwind CSS, but you can customize it to fit your design.

import { extendTheme } from '@chakra-ui/react'

});

Breakpoints#

Chakra UI comes with a predefined set of commonly used breakpoints.

import { extendTheme } from '@chakra-ui/react'

const breakpoints = {
  base: '0em',
  sm: '30em',
  md: '48em',
  lg: '62em',
  xl: '80em',
  '2xl': '96em',
}

const theme = extendTheme({ breakpoints, ... })

Spacing#

The space key allows you to customize the global spacing and sizing scale for your project. By default these spacing value can be referenced by the padding, margin, and top, left, right, bottom styles.

import { extendTheme } from '@chakra-ui/react'

const spacing = {
  space: {
    px: '1px',
    0.5: '0.125rem',
    1: '0.25rem',
    1.5: '0.375rem',
    2: '0.5rem',
    2.5: '0.625rem',
    3: '0.75rem',
    3.5: '0.875rem',
    4: '1rem',
    5: '1.25rem',
    6: '1.5rem',
    7: '1.75rem',
    8: '2rem',
    9: '2.25rem',
    10: '2.5rem',
    12: '3rem',
    14: '3.5rem',
    16: '4rem',
    20: '5rem',
    24: '6rem',
    28: '7rem',
    32: '8rem',
    36: '9rem',
    40: '10rem',
    44: '11rem',
    48: '12rem',
    52: '13rem',
    56: '14rem',
    60: '15rem',
    64: '16rem',
    72: '18rem',
    80: '20rem',
    96: '24rem',
  },
}

const theme = extendTheme({ ...spacing })

By default, Chakra includes a comprehensive numeric spacing scale inspired by Tailwind CSS. The values are proportional, so 1 spacing unit is equal to 0.25rem, which translates to 4px by default in common browsers.

Mental model: If you need a spacing of 40px, divide it by 4. That'll give you 10. Then use it in your component.

Name	Space	Pixels
px	1px	1px
0.5	0.125rem	2px
1	0.25rem	4px
1.5	0.375rem	6px
2	0.5rem	8px
2.5	0.625rem	10px
3	0.75rem	12px
3.5	0.875rem	14px
4	1rem	16px
5	1.25rem	20px
6	1.5rem	24px
7	1.75rem	28px
8	2rem	32px
9	2.25rem	36px
10	2.5rem	40px
12	3rem	48px
14	3.5rem	56px
16	4rem	64px
20	5rem	80px
24	6rem	96px
28	7rem	112px
32	8rem	128px
36	9rem	144px
40	10rem	160px
44	11rem	176px
48	12rem	192px
56	14rem	224px
60	15rem	240px
64	16rem	256px
72	18rem	288px
80	20rem	320px
96	24rem	384px

Sizes#

The sizes key allows you to customize the global sizing of components you build for your project. By default these sizes value can be referenced by the width, height, and maxWidth, minWidth, maxHeight, minHeight styles.

import { extendTheme } from '@chakra-ui/react'

const sizes = {
  sizes: {
    ...theme.space,
    max: 'max-content',
    min: 'min-content',
    full: '100%',
    '3xs': '14rem',
    '2xs': '16rem',
    xs: '20rem',
    sm: '24rem',
    md: '28rem',
    lg: '32rem',
    xl: '36rem',
    '2xl': '42rem',
    '3xl': '48rem',
    '4xl': '56rem',
    '5xl': '64rem',
    '6xl': '72rem',
    '7xl': '80rem',
    '8xl': '90rem',
    container: {
      sm: '640px',
      md: '768px',
      lg: '1024px',
      xl: '1280px',
    },
  },
}

const theme = extendTheme({ sizes, ...})

A component like this: <Box w={4} h={3} /> will generate an empty div with width set to 1rem or 16px and height set to 0.75rem or 12px.

Border radius#

Chakra provides a set of smooth corner radius values defined by the radii key.

import { extendTheme } from '@chakra-ui/react'

const borderRadius = {
  radii: {
    none: '0',
    sm: '0.125rem',
    base: '0.25rem',
    md: '0.375rem',
    lg: '0.5rem',
    xl: '0.75rem',
    '2xl': '1rem',
    '3xl': '1.5rem',
    full: '9999px',
  },
}

const theme = extendTheme({ ...borderRadius, ...})

z-index values#

Chakra provides a minimal set of z-Indices out of the box to help control the stacking order of components.

import { extendTheme } from '@chakra-ui/react'

const zIndices = {
  hide: -1,
  auto: 'auto',
  base: 0,
  docked: 10,
  dropdown: 1000,
  sticky: 1100,
  banner: 1200,
  overlay: 1300,
  modal: 1400,
  popover: 1500,
  skipLink: 1600,
  toast: 1700,
  tooltip: 1800,
}
const theme = extendTheme({ zIndices, ...})

Config#

The theme's config is to provide global settings that are used by different parts of the Chakra UI system.

Property	Description	Default
`cssVarPrefix` (v1.4)	The prefix to use for the generated CSS custom properties	`chakra`
`initialColorMode`	The initial color mode your application should start with. Can be `light`, `dark` or `system`	`light`
`useSystemColorMode`	If `true`, the chakra system will update color mode based on your system preferences	`false`

You can leverage the extendTheme function to override a specific theme config property.

import { extendTheme } from '@chakra-ui/react'

const theme = extendTheme({
  config: {
    cssVarPrefix: 'ck',
  },
})
