Skeleton

Skeleton is used to display the loading state of some component.

Source Theme Source @chakra-ui/skeleton

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

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

Theming properties#

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

variant: The visual variant of the skeleton.
colorScheme: The color scheme of the skeleton.
size: The size of the skeleton.

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'

Adding a custom variant#

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

const $startColor = cssVar('skeleton-start-color')
const $endColor = cssVar('skeleton-end-color')

const red = defineStyle({
  _light: {
    [$startColor.variable]: 'colors.red.100', //changing startColor to red.100
    [$endColor.variable]: 'colors.red.400', // changing endColor to red.400
  },
  _dark: {
    [$startColor.variable]: 'colors.red.800', //changing startColor to red.800
    [$endColor.variable]: 'colors.red.600', // changing endColor to red.600
  },
})
export const skeletonTheme = defineStyleConfig({
  variants: { red },
})

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

import { extendTheme } from '@chakra-ui/react'
import { skeletonTheme } from './components/skeleton'
export const theme = extendTheme({
  components: { Skeleton: skeletonTheme },
})

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

Adding a custom size#

Let's assume we want to include an extra large skeleton size. Here's how we can do that:

import { defineStyle, defineStyleConfig } from '@chakra-ui/react'
const xl = defineStyle({
  h: 9,
  borderRadius: 'lg',
})
export const skeletonTheme = defineStyleConfig({
  sizes: { xl },
})
// Now we can use the new `xl` size
<Skeleton size="xl">...</Skeleton>

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

Changing the default properties#

Let's assume we want to change the default size or variant of every Skeleton in our app. Here's how we can do that:

import { defineStyleConfig } from '@chakra-ui/react'
export const skeletonTheme = defineStyleConfig({
  defaultProps: {
    size: 'xl',
    variant: 'red',
  },
})
// This saves you time, instead of manually setting the size,
// variant and color scheme every time you use a skeleton:
<Skeleton size="lg" variant="red">...</Skeleton>
