C: description
D: icon
E: spinner

Theming properties#

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

variant: The visual variant of the alert. Defaults to subtle.
colorScheme: The color combination of the alert. Defaults to blue.

Theming utilities#

createMultiStyleConfigHelpers: a function that returns a set of utilities for creating style configs for a multipart component (definePartsStyle and defineMultiStyleConfig).
definePartsStyle: a function used to create multipart style objects.
defineMultiStyleConfig: a function used to define the style configuration for a multipart component.

import { alertAnatomy } from '@chakra-ui/anatomy'
import { createMultiStyleConfigHelpers } from '@chakra-ui/react'

const { definePartsStyle, defineMultiStyleConfig } =
  createMultiStyleConfigHelpers(alertAnatomy.keys)

Customizing the default theme#

import { alertAnatomy } from '@chakra-ui/anatomy'
import { createMultiStyleConfigHelpers } from '@chakra-ui/react'

const { definePartsStyle, defineMultiStyleConfig } =
  createMultiStyleConfigHelpers(alertAnatomy.keys)

const baseStyle = definePartsStyle({
  // define the part you're going to style
  title: {
    fontFamily: 'mono', // change the font family
    color: 'teal.500', // change the input text color
  },
})

export const alertTheme = defineMultiStyleConfig({ baseStyle })

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

import { extendTheme } from '@chakra-ui/react'
import { alertTheme } from './components/alert'

export const theme = extendTheme({
  components: { Alert: alertTheme },
})

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

Adding a custom size#

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

import { alertAnatomy } from '@chakra-ui/anatomy'
import { createMultiStyleConfigHelpers, defineStyle } from '@chakra-ui/react'

const { definePartsStyle, defineMultiStyleConfig } =
  createMultiStyleConfigHelpers(alertAnatomy.keys)

const xl = defineStyle({
  fontSize: 'lg',
  px: '4',
  h: '12',
})

const sizes = {
  xl: definePartsStyle({ title: xl, description: xl }),
}

export const alertTheme = defineMultiStyleConfig({ sizes })

// Now we can use the new `xl` size
<Alert size="xl" ... />

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.

Adding a custom variant#

Let's assume we want to include a custom variant. Here's how we can do that:

import { alertAnatomy } from '@chakra-ui/anatomy'
import { createMultiStyleConfigHelpers, defineStyle } from '@chakra-ui/react'

const { definePartsStyle, defineMultiStyleConfig } =
  createMultiStyleConfigHelpers(alertAnatomy.keys)

const customVariant = definePartsStyle({
  container: {
    border: '1px solid',
    borderColor: 'gray.200',
    background: 'gray.50',

    // Let's also provide dark mode alternatives
    _dark: {
      borderColor: 'gray.600',
      background: 'gray.800',
    },
  },
  title: {
    color: 'teal.500',
    _dark: {
      color: 'cyan.400',
    },
  },
})

export const alertTheme = defineMultiStyleConfig({
  variants: { custom: customVariant },
})

// Now we can use the new `custom` variant
<Alert variant="custom" ... />

Changing the default properties#

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

import { alertAnatomy } from '@chakra-ui/anatomy'
import { createMultiStyleConfigHelpers, defineStyle } from '@chakra-ui/react'

const { defineMultiStyleConfig } = createMultiStyleConfigHelpers(
  alertAnatomy.keys,
)

export const alertTheme = defineMultiStyleConfig({
  defaultProps: {
    size: 'xl',
    variant: 'custom',
  },
})

// This saves you time, instead of manually setting the size and variant every time you use an input:
<Alert size="xl" variant="custom" ... />

Showcase#

import {
  Box,
  useColorMode,
  IconButton,
  Alert,
  AlertDescription,
  AlertIcon,
  AlertTitle,
} from "@chakra-ui/react";
import { FaMoon, FaSun } from "react-icons/fa";

export default function App() {
  const { toggleColorMode, colorMode } = useColorMode();

  return (
    <Box pt={12} position="relative" h="100vh">
      <Alert size="md" status="error">
        <AlertIcon />
        <AlertTitle>Your browser is outdated!</AlertTitle>
        <AlertDescription>
          Your Chakra experience may be degraded.
        </AlertDescription>
      </Alert>

      <IconButton
        aria-label="toggle theme"
        rounded="full"
        size="xs"
        position="absolute"
        bottom={4}
        left={4}
        onClick={toggleColorMode}
        icon={colorMode === "dark" ? <FaSun /> : <FaMoon />}
      />
    </Box>
  );
}
