Hi! The way that i recommend for doing overlays is with either the ::after or ::before pseudoelement, here i did an example of a functional overlay for your card:
First of all, you will need to put your .nft image in a container, in this example i used a <div> container with the .overlay class:
<div class="overlay">
<img src="/images/image-equilibrium.jpg" alt="NFT" class="nft">
</div>
Then, you will need to make your ::after or ::before pseudoelement, in this case i used an ::after pseudoelement:
.overlay::after {
content: "";
position: absolute;
inset: 0;
background-color: #ff000087;
transform: translateX(100%);
background-image: (Your eye icon here);
transition: .3s;
border-radius: 8px;
}
//You also need to put a overflow::hidden; property inside your .overlay class, thats because im using a transform: translateX; to hide the overlay
.overlay {
position: relative;
overflow: hidden;
}
And with that you're almost done! Now we just need to show the overlay when you hover the cursor on the image:
.overlay:hover::after {
transform: translatex(0);
}
With this you will have a working overlay effect, you can customize it as you like of course. Hope that it helps!
PD: You should also add a display:block;
property to your .nft image, this is to prevent a little gap between the parent container and the image
