REST Countries API single-page app using Angular

Very unsure about how I handled accessibility on this one. I found the design itself fairly difficult to make accessible, since it's so minimalistic, so I worry I've overdone it with the ARIA instead to try and make up for it, only to make it worse. Feedback on that matter would be greatly appreciated.

Overall though, this was a rewarding project and allowed me to tackle many different aspects of Angular. I found myself struggling with things I expected to be easier, but it was worth it for all the learnings that came with the struggles.
