CSS3 3d perspective cannot be completed without the perspective attribute
CSS3 3D Transform's pivot point is in front of the browser !
Or do you understand that: the perspective point of the 3D effect element in the display is above the monitor (not the back), which is approximately where our eyes are!
For example, a 1680-pixel-wide display has a beautiful picture of a beauty, applied 3D transform, and the element or the element's parent element is set to a perspective size of 2000 pixels. The beauty of this beautiful multi-3D effect is the same as you personally in 1.2 display width of the place (1680*1.2≈2000) See the true effect of the same!!
Perspective-origin Pivot Point
This is not quite clear:
Cube: perspective-origin:25% 75%;
Transform-style:preserve-3d
Basically, we want to achieve some 3D effects based on real-world experience transform-style: preserve-3d .
In general, the Declaration is applied to the parent element of the 3D transform's sibling element, the stage element.
