Transform-style:flat | preserve-3d;
3d Perspective Properties. This property is declared on the parent element for how the child element renders in 3d space relative to its parent element, and his child elements use transform to be valid. There are two attribute values, one is the flat plane, which is also the default, and the other is preserve-3d when the child element uses transform, the position that retains its 3d is the 3d perspective. In this example, the 3d menu rollover animation uses the transform 3d warp properties, including rotation and movement. When the mouse moves into the menu, the element does a 3d flip animation; When the mouse leaves, revert to the original state
