Earlier quoted context omitted.
It's done in CSS3 + JS, so it should be pretty easy. https://desandro.github.io/3dtransforms/examples/card-01.htm... #card.flipped { -webkit-transform: rotateY( 180deg ); -moz-transform: rotateY( 180deg ); -o-transform: rotateY( 180deg ); transform: rotateY( 180deg ); }
Sure but implementing the card back image is more difficult, which is what I think the parent post was getting at, rather than the flipping itself. The rest of the page is implemented without any images, which is neat; you'd have to work some SVG magic or something to create e.g. a Bicycle-esque card back without loading an image.
I like the svg suggestion.
