Responsive bakery shop (html, css, js, react)

What are you most proud of, and what would you do differently next time?

This is my first challange from "junior" category so maybe it's not perfect but I am proud of my work. I've been working with react framework only for about 2 weeks now so I wanted to put it to a test.

What challenges did you encounter, and how did you overcome them?

Definitly managing cart future was the hardest for me since I had to work with a state of the app and I am new to this but reading documentation and having a good plan beforehand helped a lot.

What specific areas of your project would you like help with?

Do you think that it will be possible to find my first job only with plain css or should I learn bootstrap or sass. Mainly I want to know if I should focus more on JS, React or should I give more attention to styling?
