Stats Preview Card using Flebox

This was my first time using Flexbox. I learned about how to implement it far into my initial build and instead of starting over, I just tried to squeeze it in where I thought it was appropriate. This caused some issues that I eventually worked out, but I'm wondering if I have some foux pas in the way I implemented it.

Besides, general flow of my code, can you specifically look at the way I implemented Flexbox and give me any feedback (to-dos as well as not-to-dos)?

It would also be nice to have some of the good things I did reinforced as well. My greatest insecurity is writing poorly formatted or "sloppy" code. So it would be good to know when I'm doing some things right.

Thanks for the help.

Cheers!
