# Google Font Display
### Why This Error Occurred
For a Google Font, the `display` descriptor was either not assigned or set to `auto`, `fallback`, or `block`.
### Possible Ways to Fix It
For most cases, the best font display strategy for custom fonts is `optional`.
```jsx
import Head from 'next/head'
export default function IndexPage() {
return (
)
}
```
Specifying `display=optional` minimizes the risk of invisible text or layout shift. If swapping to the custom font after it has loaded is important to you, then use `display=swap` instead.
### When Not To Use It
If you want to specifically display a font using a `block` or `fallback` strategy, then you can disable this rule.
