Now that Opera Developer 19.0 supports 3D animation we can make some progress with using these styles to produce a photo gallery using just CSS.

The above demo is based on a simple 3D flip card but adapted to allow for both portrait and landscape photos with captions.

Just click/tap the image to see it flip and rotate showing the image on the reverse. There are six images in this set, but the code and stylesheet can be adjusted to show more or less images.

Firefox is still a little jerky in its animation, but all other browsers are smooth.
