perspective()

The perspective() CSS function defines a transformation that sets the distance between the user and the z=0 plane, the perspective from which the viewer would be if the 2-dimensional interface were 3-dimensional. Its result is a <transform-function> data type.

Try it

The perspective() transform function is part of the transform value applied on the element being transformed. This differs from the perspective and perspective-origin properties which are attached to the parent of a child transformed in 3-dimensional space.

Syntax

The perspective distance used by perspective() is specified by a <length> value, which represents the distance between the user and the z=0 plane, or by none. The z=0 plane is the plane where everything appears in a 2-dimensional view, or the screen. Negative values are syntax errors. Values smaller than 1px (including zero) are clamped to 1px. Values other than none cause elements with positive z positions to appear larger, and elements with negative z positions to appear smaller. Elements with z positions equal to or larger than the perspective value disappear as though they are behind the user. Large values of perspective represent a small transformation; small values of perspective() represent a large transformation; perspective(none) represents perspective from infinite distance and no transformation.

perspective(d)

Values

d: Is a <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 ℝ^2	Homogeneous coordinates on ℝℙ^2	Cartesian coordinates on ℝ^3	Homogeneous coordinates on ℝℙ^3
This transformation applies to the 3D space and can't be represented on the plane.		This transformation is not a linear transformation in ℝ^3, and can't be represented using a Cartesian-coordinate matrix.	$(\begin{matrix} 1 & 0 & 0 & 0 \\ 0 & 1 & 0 & 0 \\ 0 & 0 & 1 & 0 \\ 0 & 0 & - 1 / d & 1 \end{matrix})$
