In this example, the `TabbedPage` element contains two `ContentPage` elements with their respective contents. The `FixedEffect.VerticalPosition` property is set to `"Bottom"` to indicate that the fixed footer should be placed at the bottom of the screen. The `FixedEffect` element is then used to wrap a `StackLayout` containing a `Label` that will serve as the fixed footer. The `Height` property is set to `50` to define the height of the fixed footer. Overall, the csharp Server Mobile FixedEffect package library enables developers to create more engaging and user-friendly mobile applications by adding fixed effects to their layouts.
