perspective-origin
The perspective-origin
CSS property determines the position at which the viewer is looking. It is used as the vanishing point by the perspective
property.
Try it
The perspective-origin
and perspective
properties are attached to the parent of a child transformed in 3-dimensional space, unlike the perspective()
transform function which is placed on the element being transformed.
