NFT Card using SASS and CSS Flex Box

What I found most difficult was to superimpose 2 images. I have 2 questions:

• Is there an easier way to overlay 2 images with SASS or vanilla CSS than using the position property?
• Do you think I have a good code?

I really had problems because I didn't know how to use the position property correctly, but I was watching many tutorials and finally I managed to understand how to use it and I could finish this challenge.
