# Display a map with a custom style
Use a Mapbox-hosted custom [style](https://docs.mapbox.com/help/glossary/style/) in a Mapbox GL JS map. This example uses a copy of Taya Lavrinenko's [The Happy Map](https://medium.com/mapbox/doh-making-a-simspons-inspired-map-with-expressions-86e633b61ede) style.
> Example code:
**JavaScript**
```html
Display a map with a custom style
```
**React**
```jsx
import React, { useEffect, useRef } from 'react';
import * as mapboxgl from 'mapbox-gl/esm';
import 'mapbox-gl/dist/mapbox-gl.css';
const MapboxExample = () => {
const mapContainerRef = useRef();
const mapRef = useRef();
useEffect(() => {
mapRef.current = new mapboxgl.Map({
// TO MAKE THE MAP APPEAR YOU MUST
// ADD YOUR ACCESS TOKEN FROM
// https://account.mapbox.com
accessToken: 'YOUR_MAPBOX_ACCESS_TOKEN',
container: mapContainerRef.current,
style: 'mapbox://styles/examples/cke97f49z5rlg19l310b7uu7j',
center: [41, 21],
zoom: 3
});
return () => {
mapRef.current.remove();
};
}, []);
return ;
};
export default MapboxExample;
```
