## Example

Here's an example of how to customize breakpoints in Chakra UI.

```tsx title="theme.ts"
import { createSystem, defaultConfig, defineConfig } from "@chakra-ui/react"

const config = defineConfig({
  theme: {
    breakpoints: {
      tablet: "992px",
      desktop: "1200px",
      wide: "1400px",
    },
  },
})

export default createSystem(defaultConfig, config)
```

## Usage

When using responsive properties, reference the new breakpoints.

```tsx title="App.tsx"
<Box fontSize={{ base: "16px", tablet: "18px", desktop: "20px" }}>Hello</Box>
```
