As a first-year CS student in university, I have been diving into the world of React.js. Currently, I am exploring a resume project and noticed that both app.js and index.js files are empty. I am curious to know how the styling is achieved in this project. While I see className attributes within JSX elements of the components, I can't seem to find a related CSS file in the src folder. Could it possibly be located inside the public folder instead? In addition to answering my questions, feel free to suggest any React topics or techniques I should study to gain a better understanding of how the styling is implemented here.

I have researched topics like how styling works for components in React.js, but haven't found a definitive answer yet.
