The first element to set is the perspective
. The perspective is what gives us the 3D impression. The farther from the viewer the elements are, the smaller they are.
Setting perspective
This example shows a cube with the perspective set at different positions. How quick the cube shrinks is defined by the perspective
property. The smaller its value is, the deeper the perspective is.
HTML
The HTML below creates four copies of the same box, with the perspective set at different values.
<table>

CSS
The CSS establishes classes that can be used to set the perspective to different distances. It also includes classes for the container box and the cube itself, as well as each of its faces.
.pers250 {
perspective: 250px;
}
.pers350 {

.right {
background: rgba(196, 0, 0, 0.7);
transform: rotateY(90deg) translateZ(50px);
}
.left {
background: rgba(0, 0, 196, 0.7);
transform: rotateY(-90deg) translateZ(50px);
}
.top {
background: rgba(196, 196, 0, 0.7);
transform: rotateX(90deg) translateZ(50px);
}
.bottom {
background: rgba(196, 0, 196, 0.7);
transform: rotateX(-90deg) translateZ(50px);
}
th,
p,
td {
background-color: #eeeeee;
padding: 10px;
font-family: sans-serif;
text-align: left;
}
Result
The second element to configure is the position of the viewer, with the perspective-origin
property. By default the perspective is centered on the viewer, which is not always adequate.
Changing the perspective origin
This example shows cubes with popular perspective-origin
values.
