CSS Function - matrix()

Quiz

The CSS function matrix() defines a 2D transformation matrix with homogeneous coordinates, resulting in a data type of transform().

Possible Values

a b c d - These are <number>s describing the linear transformation.
tx ty - These are <number>s describing translation to apply.

The values represent the following functions: matrix(scaleX(), skewY(), skewX(), scaleY(), translateX(), translateY())

Syntax

The matrix() is a 4x4 matrix, but only the first 6 values are used for 2D transformations. The function has the following syntax:

matrix(a, b, c, d, tx, ty)

a (m11): Horizontal scaling.
b (m12): Vertical skewing.
c (m21): Horizontal skewing.
d (m22): Vertical scaling.
e (dx): Horizontal translation.
f (dy): Vertical translation.

The matrix() function is used to combine multiple transformations into a single transform property.

      font-size: 24px;
      text-align: center;
   }
</style>
</head>
<body>
   <div class="matrix-demo">This is a matrix div</div>
   <div class="normal-demo">This is a normal div</div>
</body>
</html>
