NFT Preview Card Component

So I learned a lot doing this one. But I really struggled with trying to get the image to transition to the view and overlay color. I did not succeed in that portion and any advice would be nice.

I finally feel like I understood how to properly position it in the center of the page, which is great because I didn't have to use extra margin to get it positioned correctly, so that's a positive.

I need to work more on planning out my divs better, I realize that each time I do these, and thought I had it under control this time, but still found points where I confused myself.

All the designs I make seem to end up smaller than the original design and I'm not sure how to fix that or plan for it. Advice on that would be helpful as well.
