Responsive REST Countries API with color theme switcher

My solution for challenge REST Countries API with color theme switcher.

This was a super complex challenge using third party API, the looks are not exactly the same as in the design but the highlight for me was the JavaScript in the background.

I should have refactored the JavaScript more, I might do it later but right now I am pretty satisfied with the result.

As usual, any comments / advice is more then welcome.

Thanks :)
