REST countries API with color theme switcher reponsive

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

during coding I captured the process to add the animations with js, so I tried to implement it as best as I could, so next time I will create even more impressive animations than the one I I created in this project.

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

initially the javascript fetch API sent me CORS errors telling me I was not authorized to access the data.json file, I searched and finally realized that it was not was not possible to access the date by file\\\: but rather not http:// or https://. therefore passed through a web server.

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

nowhere at the moment.
