title: 'Invalid `styled-jsx` children'
---

## Why This Error Occurred

You have passed invalid children to a `<style jsx>` tag.

## Possible Ways to Fix It

Make sure to only pass one child to the `<style jsx>` tag, typically a template literal.

```jsx filename="example.js"
const Component = () => (
  <div>
    <p>Red paragraph</p>
    <style jsx>{`
      p {
        color: red;
      }
    `}</style>
  </div>
)
```
