NFT preview card component challenge

Hi Frontend Mentor peers~

I am uploading this challenge knowing that I haven't complete all the requirement and I need some help.

I have trouble figuring how to make the image to show the viewing icon when the cursor hovers over it, and I don't know where to begin looking for help. I'd appreciate if you can give me some guidance, including good online resources to read, to help me understand what I need to learn.

Secondly, if you have any additional tips on how to improve my code, it's greatly appreciated. #bestpractices

Thank you!
