In Lightswitch development, the application’s main window is divided into three main parts:
1. Ribbon: This area at the top of the screen gives quick access to common tasks which are performed in the LightSwitch application.
2. Navigation Pane: On the left of the screen the Navigate Pane lists the apps screens.
3. Main Pane: The main active working screen. To change screens click another screen from the Navigation View.
Using these parts, you can easily design the login page. For more details, refer
