REST countries API with color theme switcher

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

I think I got the design and functionality close to the requirements (though the design is a bit off).

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

For some reason, the theme changes for things like the input and filter didn't work with Vue so I had to use CSS. Not sure how to fix it.

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

How can I dynamically change the theme of the elements in dark mode using Vue instead of CSS?
