How does the display content change if you rotate the device 90 degrees?

When rotating the device 90 degrees (for example, from portrait to landscape mode), the screen orientation changes, which affects the display of content:

• The interface automatically reconfigures if the app supports responsive design.
• UI elements may change their size and position to better utilize the available space.
• If the app does not support rotation, the screen may lock or the content will be displayed in the previous orientation.

In iOS, rotation handling uses view controller lifecycle methods and auto layout, which automatically adapts the interface to the new orientation.
