Please read the [overview](/docs/theming/customization/overview) first to learn
how to properly customize the styling engine, and get type safety.

## Recipes
### Extending variants
Use the `defineRecipe` function to define a recipe override.
Here's an example of extending the `Button` to add a new `xl` size
```tsx title="theme.ts"
const buttonRecipe = defineRecipe({
variants: {
size: {
xl: {
fontSize: "lg",
px: 6,
py: 3,
},
},
},
})
const customConfig = defineConfig({
theme: {
recipes: {
button: buttonRecipe,
},
},
})
export const system = createSystem(defaultConfig, customConfig)
```
Then you can use the new size variant in your components.
```tsx
```
### Adding new variant
Use the `defineRecipe` function to define a new recipe variant.
Here's an example of defining a boolean variant called `raised`.
```tsx title="theme.ts"
const buttonRecipe = defineRecipe({
variants: {
raised: {
true: {
boxShadow: "md",
},
},
},
})
const customConfig = defineConfig({
theme: {
recipes: {
button: buttonRecipe,
},
},
})
export const system = createSystem(defaultConfig, customConfig)
```
Then you can use the new variant in your components.
```tsx
```
### Custom recipe
Use the `defineRecipe` function to define a custom recipe all together.
Here's an example of defining a custom recipe called `Title`
```tsx title="theme.ts"
const titleRecipe = defineRecipe({
baseStyle: {
fontWeight: "bold",
letterSpacing: "tight",
},
variants: {
size: {
md: { fontSize: "xl" },
lg: { fontSize: "2xl" },
},
},
})
const customConfig = defineConfig({
theme: {
recipes: {
title: titleRecipe,
},
},
})
export const system = createSystem(defaultConfig, customConfig)
```
Then, use the new recipe to create a components
```tsx
const Title = (props) => {
const recipe = useRecipe({ key: "title" })
const styles = recipe({ size: "lg" })
return
}
```
## Slot Recipes
To effectively override an existing slot recipe, we recommend connecting to its
anatomy. Slot recipes are added to the `theme.slotRecipes` object.
### Extending variants
Here's an example of how to extend the `Alert` slot recipe to create an `xl`
size.
```tsx title="theme.ts"
import { alertAnatomy } from "@chakra-ui/react/anatomy"
const alertSlotRecipe = defineSlotRecipe({
slots: alertAnatomy.keys(),
variants: {
size: {
xl: {
root: {
fontSize: "lg",
px: 6,
py: 3,
},
},
},
},
})
const customConfig = defineConfig({
theme: {
slotRecipes: {
alert: alertSlotRecipe,
},
},
})
export const system = createSystem(defaultConfig, customConfig)
```
Then you can use the new size variant in your components.
```tsx /size="xl"/
```
### Adding new variant
Here's an example of how to extend the `Alert` slot recipe to add a new variant
called `shape`.
```tsx title="theme.ts"
import { alertAnatomy } from "@chakra-ui/react/anatomy"
const alertSlotRecipe = defineSlotRecipe({
slots: alertAnatomy.keys(),
variants: {
shape: {
rounded: {
root: { borderRadius: "full" },
},
},
},
})
const customConfig = defineConfig({
theme: {
slotRecipes: {
alert: alertSlotRecipe,
},
},
})
export const system = createSystem(defaultConfig, customConfig)
```
Then you can use the new variant in your components.
```tsx /shape="rounded"/
```
### Custom recipe
Here's an example of how to define a custom slot recipe called `Navbar`.
```tsx title="theme.ts"
const navbarSlotRecipe = defineSlotRecipe({
slots: ["root", "badge", "icon"],
base: {
root: {
bg: "blue.500",
color: "white",
px: 4,
py: 2,
},
badge: {
borderRadius: "full",
px: 2,
py: 1,
},
},
})
const customConfig = defineConfig({
theme: {
slotRecipes: {
navbar: navbarSlotRecipe,
},
},
})
export const system = createSystem(defaultConfig, customConfig)
```
Then you can use the new recipe to create a components
```tsx
const Navbar = (props) => {
const recipe = useSlotRecipe({ key: "navbar" })
const styles = recipe()
return (
{props.children}
)
}
```
