The perspective()
CSS function defines a transformation that sets the distance between the user and the z=0 plane. Its result is a <transform-function>
data type.
The perspective distance used by perspective()
is specified by a <length>
value, which represents the distance between the user and the z=0 plane. A positive value makes the element appear closer to the user, a negative value farther.
perspective(d)
<length>
representing the distance from the user to the z=0 plane. If it is 0 or a negative value, no perspective transform is applied.Cartesian coordinates on ℝ2 | Homogeneous coordinates on ℝℙ2 | Cartesian coordinates on ℝ3 | Homogeneous coordinates on ℝℙ3 |
---|---|---|---|
This transformation applies to the 3D space and can't be represented on the plane. | This transformation is not a linear transformation in ℝ3, and can't be represented using a Cartesian-coordinate matrix. |
