Make the App look good!

Today, I added a stylesheet (made by AI) to make my app look more modern and appealing. Since I am coding the structure of the app, this is ok. Along the way, I learned how to incorporate CSS as classes in both HTML and JavaScript. I also learned that JavaScript uses the classListadd method to add classes, while HTML is just a direct type-in. I am hoping to learn more CSS in the process. My next step is to add new components such as a sidebar and more interactive features.
