REST Countries API with color theme switcher using React and Tailwind

Hello ladies and gentlemen! This is my first React app on here. There's a couple of bits I struggled with so I've just left them out:

• The border links on the country detail page
• Having proper slugs for each of the country detail pages e.g. /country/czech-republic

Also, tried looking into using local storage to persist some react state so that it remembers whether dark mode is on or not, but I sacked that off as well.

I'm open to some lovely feedback from all of you. Thank you! 😅
