The matrix3d() CSS function defines a 3D transformation as a 4x4 homogeneous matrix. Its result is a <transform-function> data type.

matrix3d(a1, b1, c1, d1, a2, b2, c2, d2, a3, b3, c3, d3, a4, b4, c4, d4) 

matrix3d()

The matrix3d() CSS function defines a 3D transformation as a 4x4 homogeneous matrix. Its result is a <transform-function> data type.

Syntax

The matrix3d() function is specified with 16 values. They are described in the column-major order.

matrix3d(a1, b1, c1, d1, a2, b2, c2, d2, a3, b3, c3, d3, a4, b4, c4, d4) 

Values

a1 b1 c1 d1 a2 b2 c2 d2 a3 b3 c3 d3

Are <number>s describing the linear transformation.

a4 b4 c4 d4

Are <number>s describing the translation to apply.

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.		A generic 3D affine transformation can't be represented using a Cartesian-coordinate matrix, as translations are not linear transformations.	( a1 a2 a3 a4 b1 b2 b3 b4 c1 c2 c3 c4 d1 d2 d3 d4 )

Examples

Cube squashing example

The following example shows a 3D cube created from DOM elements and transforms, which can be hovered/focused to apply a matrix3d() transform to it.

HTML

<section id="example-element" tabindex="0">   <div class="face front">1</div>   <div class="face back">2</div>   <div class="face right">3</div>   <div class="face left">4</div>   <div class="face top">5</div>   <div class="face bottom">6</div> </section> 

CSS

#example-element {   width: 100px;   height: 100px;   transform-style: preserve-3d;   transition: transform 1.5s;   transform: rotate3d(1, 1, 1, 30deg);   margin: 50px auto; }  #example-element:hover, #example-element:focus {   transform: rotate3d(1, 1, 1, 30deg) matrix3d(1,0,0,0,0,1,6,0,0,0,1,0,50,100,0,1.1); }  .face {   display: flex;   align-items: center;   justify-content: center;   width: 100%;   height: 100%;   position: absolute;   backface-visibility: inherit;   font-size: 60px;   color: #fff; }  .front {     background: rgba(90,90,90,.7);     transform: translateZ(50px); }  .back {     background: rgba(0,210,0,.7);     transform: rotateY(180deg) translateZ(50px); }  .right {   background: rgba(210,0,0,.7);   transform: rotateY(90deg) translateZ(50px); }  .left {   background: rgba(0,0,210,.7);   transform: rotateY(-90deg) translateZ(50px); }  .top {   background: rgba(210,210,0,.7);   transform: rotateX(90deg) translateZ(50px); }  .bottom {   background: rgba(210,0,210,.7);   transform: rotateX(-90deg) translateZ(50px); }
