Is my answer in the css correct?

for me the code seems correct, I don't know what can be wrong

style.css 
/* Complete the challenge by writing CSS below */

.wrapper {
  perspective: 600px;
}

.photo {
  transform: rotateY(30deg)
}
index.html 
<!DOCTYPE html>

Hi there! Your answer is partially correct. It would have the same effect as what they're asking for, but the challenge explicitly asks for the 3d version of the rotation. Take another look at the Bummer! message:

Bummer! Make sure you're using the 3D-specific function for rotations.

So this is what they're looking for:

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

This is the rotate3d specific form of what you've written. The first three numbers will be either 0 or 1. A one indicates the axis that should be rotated on. The fourth and final number indicates the degrees.

Hope this helps! :sparkles:
