Wikipedia Viewer challenge feedback

Hello everyone!

I just finished the Wikipedia Viewer challenge and I would appreciate if you could provide some feedback.

I have tried to provide a nice style to it but I am unsure about wether the overall quality is good enough. (It does fulfill the user stories, but I was wondering if it needs any further improvement towards portfolio building),

Here’s the link.
