While your code would have the same effect, it's not what they're asking you to do. They specifically state they want the 3d rotate. Take a look at my code:

.wrapper {
  perspective: 600px;

.photo {
  transform: rotate3d(0, 1, 0, 30deg);

Here we've toggled the Yaxis to "on" with the 1. Then we set the degrees at the end.

thanks for that... I also agree with David

In my opinion the challenge should have accepted Connor's solution, since "rotateY(a)is a shorthand for rotate3D(0, 1, 0, a)."

I was struggling some time with this second challenge because I used space between the word rotate3d and parenthesis :) like this "rotate3d (..." So make shore everyone not to do this little mistake.... no spaces

.photo { transform: rotate3d(0, 1, 0, 30deg); }
