React Todo App using SASS and BEM

Hi guys,

This is my first completed solution here on the frontendmentor.io and my first React application.

There are my questions:

• What could I improve related to the React and React file structuring?
• What could I improve related to the SCSS?
• Do you have any tips for better implementation of the backgrounds in the header area? Note: I tried to use the <img> element for the backgrounds but it was a little tricky since I'm using React for the first time, and I had to implement dark mode. That's why I decided to go w/css background.
• Do you have any tips for my future projects and what I could do better in this project?

Thanks,

Stefan
