The parent element to add the attribute transform-style:preserve-3d, and transform:perspective (800px), and relative positioning first set the child element with a 3D attribute, and then set the distance between the angle of view and the 3D element, You can see the 3D effect by pulling the angle! in pixels; relative positioning is to position the child element absolutely a punctuation; in a cube, for example, I only have a cube ... The child element is a cube of all facets, 6 div is 6 faces, and then absolutely positioning, out of the document flow, and make their origin coincident, convenient adjustment;::::::::.:.: This is a very important thing to think about the order of rotation and displacement according to the result of the final presentation of the graph. To rotate the axis after the change, the direction of the axis also follow the rotation estimation is this only I can understand it .... I hope I can see it a year later
A little bit of clarity about TRANSFORM-STYLE:PRESERVE-3D
