Webview with viewbox

Question

Hello,

I am trying to use a webviewer within a viewbox ,so that when it's scaled from 1366x768 to 1920x1080, and keeps the same layout (look and feel). I am unable to get it to scale correctly at 1920x1080. The webvew doesn't seem to adjust. I think I am using the correct control (Viewbox) to help with up-scaling. Any advice, I would be grateful/helpful. Here is my XAML code:

<common:LayoutAwarePage
    x:Name="pageRoot"
    x:Class="Save_It.Vacation"
    DataContext="{Binding DefaultViewModel, RelativeSource={RelativeSource Self}}"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Save_It"
    xmlns:common="using:Save_It.Common"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <Page.Resources>

        <!-- TODO: Delete this line if the key AppName is declared in App.xaml -->
        <x:String x:Key="AppName">My Application</x:String>
    </Page.Resources>

    <!--
