UWP app how to make background completely black

Question

我将页面背景设置为黑色，并且什么都不做没有问题，但是当键盘打开时单击TextBox时，或者当我将电话布局从水平更改为垂直时，当我在边缘看到白色时，如何也将它们设置为黑色？

Are you changing the page or the grid background. I would assume you are only changing the grid background not the page.

The below example is changing both the page and the grid.

<Page
    Background="Black"
    x:Class="Rasberry_Pi_Trebuchet.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Rasberry_Pi_Trebuchet"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <Grid Background="Black">

    </Grid>
</Page>
