This is the second video in a series showing off how to build your first Trivia App. This video covers the basics of editing the design of the app. There are 4 easy to-do customizable changes to the UI that require no previous XAML experience! You can change the background on every page, the color of all the UI elements, the sound effects, and update the title throughout the app. To update the background you have to replace the Background.png image in the Assets folder. To change the colors of the UI elements you have to change the SolidColorBrushes in App.xaml. To change the sound effects you have to replace the two mp3 files in the SoundEffects folder.
