CSS 3D Transforms - Perspective
CSS Perspective
To activate a 3D space, the element needs perspective. The perspective defines the distance between the user's viewpoint and the object.
A low value, like perspective: 200px;,
assumes that the user is close to the object and creates a strong 3D effect.
A high value, like perspective: 2000px;,
assumes that the user is far away from the object and creates a mild 3D effect.
Without perspective, any 3D transforms will look flat and two-dimensional.
A perspective can be added in two ways:
- With the
perspectiveproperty - With the
perspective()function
Using the perspective Property
The perspective property is always set on the parent element,
and each child will share the same 3D space.
Example
.container {
width: 180px;
height: 180px;
border:
1px solid lightgray;
margin: 30px;
perspective: 500px; /*
set perspective on parent element */
}
.box {
width:
100%;
height: 100%;
background-color: green;
transform: rotateY(45deg);
}

Using the perspective() Function
The perspective() function is used to directly apply a 3D transform
to a single element:
Example
.container {
width: 180px;
height: 180px;
border:
1px solid lightgray;
margin: 30px;
}
.box {
width:
100%;
height: 100%;
background-color: green;
/* perspective function in transform property */
transform: perspective(500px) rotateY(45deg);
}
Try it Yourself »
Both of the examples above produce the same result.
However: When you put the perspective property on a parent element, each child will share the same 3D space,
while the perspective() function is used to directly apply a 3D transform
to one single element.
