NFT Preview Card Component made w/ Flexbox

In the image, there seems to be some kind of <box-shadow>, but I'm not sure how to accomplish this. The blur doesn't seem to work that way...Unless it was simply to outline the card in the design. In which case...I added a nice <box-shadow> in order to really outline the card!

Any suggestions are welcome, particularly on the organizational side of my style.css. For some reason, I think I create too many classes when I could be using pseudo-classes or symbolic references such as >, ::after, ::before, etc.

Last but not least, the creation of <a hrefs> was a design choice as the active states could look like links to profiles. If this is not intended, then let me know the proper alternative.
