# useScreenSafeArea
|
|
|
|
Reactive `env(safe-area-inset-*)`
|
|
|
|
|
|
|
|
## 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()
|
|
```
|
|
|
|
