TODO app with Vite, React and Styled-Components

Hi! This is my first full project in React. Most than welcome with all problems or advice that you can give me. I add some extra features:

• save in localStorage task
• save in localStorage theme chosen
• first time you open app check theme system to decide between dark / ligth Some points I've struggle a little bit:
• How to make a styled checkbox. I don't know if my solution is the best.
• How to organize the project. This one doesn't have much components but I want to try different approches and see with one is best for me.

Thanks in advance!!
