NFT-card-grid-flexbox

This was my first challenge on Frontend Mentor. I would be greatly appreciative if anyone can review the way I used Flexbox and Grid together and provide feedback whether there is a better solution that what I used.

Basically, I used a large Flexbox column (body tag), Grid within the main box (container), and two Flexboxes: (1) Area with the ethereum and clock icons (2) Avatar and author area

Any other feedback would be greatly appreciated!! I am sure there are ways my code could be more concise.

Thanks!!
