Maintain and restore scroll position in React mobile apps

The text discusses a common challenge in mobile web design where a full-page navigation menu can obstruct the underlying page, leading to a poor user experience because the page should remain scrollable when the menu is open. A typical solution involves fixing the position of the page, but this can cause users to lose their scroll position when the menu closes. To address this, the text introduces a React application tutorial that demonstrates how to use a custom Hook, `useMenuControl`, to manage a full-page mobile menu while maintaining the scroll position. The Hook controls the menu's open and closed states and prevents scrolling by adjusting the document's body overflow property, allowing users to continue from their previous scroll position once the menu is closed. The tutorial provides detailed code implementation, including setting up a React application, creating a mobile navigation menu, and utilizing the custom Hook to enhance user experience.
