Mobile First NFT preview card using only HTML and CSS

What did you find difficult while building the project?

The thing i found the most difficult was to hide and show the eye image on top of the NFT main image, at first i tried to figure out by myself but had to look up for a css propertie that could help me. I found the CSS propertie vissibility that help me, also i had to combine in the same CSS rule the selector of the container with a hover and the eye image inside of it so that way i can make it appear again when i hover it

Do you have any questions about best practices?

How could i have done the show/hide feature better with only CSS and HTML? i made it using :

.eye{visibility:hidden}
.container:hover img{visibility:visible}
