title: 'No `styled-jsx` in `_document`'
|
|
---
|
|
|
|
> Prevent usage of `styled-jsx` in `pages/_document.js`.
|
|
|
|
## Why This Error Occurred
|
|
|
|
Custom CSS like `styled-jsx` is not allowed in a [Custom Document](/docs/pages/building-your-application/routing/custom-document).
|
|
|
|
## Possible Ways to Fix It
|
|
|
|
If you need shared CSS for all of your pages, take a look at the [Custom `App`](/docs/pages/building-your-application/routing/custom-app) file or define a custom layout.
|
|
|
|
For example, consider the following stylesheet named `styles.css`:
|
|
|
|
```css filename="styles.css"
|
|
body {
|
|
font-family:
|
|
'SF Pro Text', 'SF Pro Icons', 'Helvetica Neue', 'Helvetica', 'Arial',
|
|
sans-serif;
|
|
padding: 20px 20px 60px;
|
|
max-width: 680px;
|
|
margin: 0 auto;
|
|
}
|
|
```
|
|
|
|
Create a `pages/_app.{js,tsx}` file if not already present. Then, import the `styles.css` file.
|
|
|
|
```jsx filename="pages/_app.js"
|
|
import '../styles.css'
|
|
|
|
// This default export is required in a new `pages/_app.js` file.
|
|
export default function MyApp({ Component, pageProps }) {
|
|
return <Component {...pageProps} />
|
|
}
|
|
```
|
|
|
|
These styles (`styles.css`) will apply to all pages and components in your application.
