This example styles the map in night mode. It uses colors that are useful for
situations such as giving directions in the dark. In the satellite view, styling
does not affect base imagery, but it does affect roads, labels, and other map
components.

### CSS

```css
/* 
 * Always set the map height explicitly to define the size of the div element
 * that contains the map. 
 */
#map {
  height: 100%;
}

/* 
 * Optional: Makes the sample page fill the window. 
 */
html,
body {
  height: 100%;
  margin: 0;
  padding: 0;
}
```

### HTML
