Peer-to-peer-code review

I love the concept of importing the files directly into the index.js, your CSS follows the DRY, YAGNI, and KISS methods to its best, I also see the consistency, proper indentation, variable declaration, function naming, and optimization in your js. I would however recommend you cross-check your error handling in the local storage codes.
Great Job Muzammel.
