NFT Card with a little Flexbox

I noticed that below your 800px breakpoint the image is off-center, it would be worth looking into using flexbox to fix the alignment of the hero image.

.card {
    width: 95%;
    display: flex;
    flex-direction: column;
}

I would also give the image a min-width: of pixels so that it doesn't resize to be too small on the desktop view.

Here is a good resource for learning the basics of flexbox

Otherwise, great job, looks good :D
