Stats Preview Card Component with HTML and CSS (Mobile first design)

I struggled doing this challenge, but was finally able to complete it. I know that there are a lot of things to improve in terms of the sizing and just how responsive it could be.

I designed the mobile layout first and then used one media query for the desktop layout. It's only my second time using a media query (the first one is for a challenge I'm yet still to finish), so I would appreciate any feedback and insight you might have!
