![image](https://webkit.org/wp-content/uploads/safe-areas-1.png)

## Usage

In order to make the page to be fully rendered in the screen, the additional attribute `viewport-fit=cover` within `viewport` meta tag must be set firstly, the viewport meta tag may look like this:

```html
<meta name="viewport" content="initial-scale=1, viewport-fit=cover" />
```

Then we could use `useScreenSafeArea` in the component as shown below:

```ts
import { useScreenSafeArea } from '@vueuse/core'

const {
  top,
  right,
  bottom,
  left,
} = useScreenSafeArea()
```

    content
  </UseScreenSafeArea>
</template>
