Data-rotate: Rotate. Make sure to rotate your slide by a number of degrees
Data-rotate-x: For 3D, the number of degrees is how much it should rotate relative to the x-axis. (Tilt forward/back)
Data-rotate-y: For 3D, the number of degrees is how much it should rotate relative to the Y axis. (Left pendulum/Right pendulum)
Data-rotate-z: For 3D, the number of degrees is how much it should rotate relative to the z
