# Safe Area

모바일 브라우저에서는 상태바나 홈 인디케이터 같은 시스템 UI 때문에 콘텐츠가 가려질 때가 있어요. 앱인토스 SDK는 이런 상황을 방지하기 위해 화면의 안전 영역(Safe Area) 여백 값을 픽셀 단위로 계산하는 함수를 제공해요.

특히 iPhone X 이상 기기나 일부 Android 기기에서는 전체 화면을 사용하는 웹 앱에서 시스템 UI가 콘텐츠를 가리는 경우가 자주 있어요. 아래 함수를 사용하면 콘텐츠가 안전하게 표시되도록 여백을 쉽게 조절할 수 있어요.

### `useSafeAreaInsets`

모바일 브라우저에서 상태바나 홈 인디케이터 같은 시스템 UI에 의해 콘텐츠가 가려지는 문제를 방지할 수 있도록, 화면의 안전 영역(Safe Area) 여백 값을 픽셀 단위로 계산해줘요. `useSafeAreaInsets` 는 ReactNative 로 개발할 때 사용할 수 있어요.

```tsx
import { useSafeAreaInsets } from '@granite-js/native/react-native-safe-area-context';
const { top: safeAreaTop, right: safeAreaRight } = useSafeAreaInsets();
// 네비바 상단 여백: safeAreaTop
// 네비바 우측 여백: safeAreaRight + 10
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developers-apps-in-toss.toss.im/documentation/react-native/screen-navigation/safe-area.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
