 # useBodyScrollLock
 
-A React hook that locks body scroll when mounted and automatically unlocks when unmounted. This is particularly useful for modals, drawers, and other overlay components that should prevent background scrolling.

 ```ts
@@ -10,50 +8,20 @@ function useBodyScrollLock(): void;
 
 ### Parameters
 
-This hook takes no parameters.
-
 ### Return Value
 
-This hook returns `void` (no return value).
+This hook does not return anything.
 
-## Examples
-
-### Basic Usage
+## Example
 
+````tsx
 ```tsx
 function Modal() {
   useBodyScrollLock();
   return <div className="modal">Modal content</div>;
 }
-```
-
-### Multiple Modals - Single Lock Pattern
-
-When you have multiple overlapping modals, use a single lock at the parent level instead of applying the lock to each modal individually.
-
-```tsx
-// Multiple modals - single lock pattern
-function BodyScrollLock() {
-  useBodyScrollLock();
-  return null;
-}
-
-function App() {
-  const hasModal = showModal1 || showModal2;
+````

-      {showModal1 && <Modal1 />}
-      {showModal2 && <Modal2 />}
-    </>
-  );
-}
 ```
 
-## Notes
-
-- **SSR Safety**: This hook uses `useEffect`, which only runs on the client side, making it safe for server-side rendering (SSR).
-- **Automatic Cleanup**: The scroll lock is automatically removed when the component unmounts, ensuring proper cleanup.
-- **Multiple Modals**: For scenarios with multiple overlapping modals, implement a single lock at the parent level rather than applying locks to each modal individually. This prevents conflicts and ensures consistent behavior.
-- **Browser Support**: Works in all modern browsers that support the underlying CSS modifications applied by the `enableBodyScrollLock` and `disableBodyScrollLock` utilities.

-## Notes
-
-### Browser Support
-
-- **Chrome/Edge (Android)**: Full support for all properties
-- **Chrome/Edge (Desktop)**: Partial support (effectiveType, downlink, rtt, saveData available; type may be undefined)
-- **Firefox**: Not supported (all properties will be undefined)
-- **Safari**: Not supported (all properties will be undefined)
-
-### SSR Safety
-
-This hook is SSR-safe. It returns an empty object `{}` on the server and safely subscribes to network changes only in the browser environment.
-
-### Usage Recommendations
-
-1. Always check for undefined values before using them, as the API may not be supported in all browsers
-2. Provide fallback behavior for browsers that don't support the Network Information API
-3. Use the hook to enhance user experience, not as a required feature
-4. Consider combining `effectiveType` and `saveData` for optimal content delivery decisions

-## Notes
-
-- **SSR Safety**: During server-side rendering, this hook returns `{ isVisible: true, visibilityState: 'visible' }` as a safe default since the Page Visibility API is not available on the server.
-- **Browser Support**: The Page Visibility API is supported in all modern browsers. See [MDN Browser Compatibility](https://developer.mozilla.org/en-US/docs/Web/API/Page_Visibility_API#browser_compatibility) for details.
-- **Performance**: The hook uses the native `visibilitychange` event, which is highly optimized and has minimal performance impact.
-- **Visibility States**: The hook excludes the deprecated `'prerender'` state and only returns `'visible'` or `'hidden'`.
