CSS CSS Transitions and Transforms Adding 3D Effects with CSS Build a Rotating 3D Cube

If the cube is spinning from left to right or vice versa, why are using the rotateY property?

I don't understand why we're using the rotateY property to spin a cube in a horizontal fashion. My intuition makes me think it would make the cube spin up or down.

The rotation happens around the axis. It felt counter-intuitive to me at first too because the cube is rotating through the horizontal x-axis. When I thought about having three axes though, the only way you can do it is if you describe the rotation in relation to the axis it is rotating around rather than through.
