Updated Challenge Solution

I found that the hardest part of this challenge was deciding what the most efficient way to write my code was. This is the first "challenge" I've done and that made it intimidating and I found myself stressing over making sure my code could be understood (which is a good thing). I have a lot of uncertainties with my code i.e. what is the better way of formatting my CSS? I used flex to do the formatting, but did that maybe make my code messy? What about my HTML? Is nesting that many divs even necessary for what I was trying to accomplish? I'm self-taught so finer details of coding are lost in the teachings and I'd appreciate any and all feedback anyone takes the time to give me about this first try. Please go over the README.md in the repo for more info on my process.
