Common CSS styles (3)

1. 2D transformation

　1. transform Set or retrieve the transformation of the object

Value:

　 none: Specify a 2D transformation in the form of a six-value (a, b, c, d, e, f) transformation matrix, which is equivalent to directly applying a [a, b, c, d, e, f] Transformation matrix

translate([, ]). The first parameter corresponds to the X-axis, and the second parameter corresponds to the Y-axis. If the second parameter is not provided, the default value is 0.              

TranslateX(): Specifies the translation of the X-axis (horizontal direction) of the object

　translateY(): Specify the translation of the Y-axis (vertical direction) of the object

rotate(): Specify the 2D rotation of the object. The first parameter corresponds to the X-axis, and the second parameter corresponds to the Y-axis. If the second parameter is not provided, the value of the first parameter will be taken by default

scaleX(): Specifies the (horizontal) scaling of the X-axis of the object

　scaleY(): Specifies the (vertical) scaling of the Y-axis of the object

skew( [, ]): Specify object skew transformation (oblique distortion). The first parameter corresponds to the X-axis, and the second parameter corresponds to the Y-axis. If the second parameter is not provided, the default value is 0 skewX(): Specifies the (horizontal) distortion of the object's X-axis

　skewY(): Specifies the (vertical) distortion of the Y-axis of the object

　Note: Different browsers require the following prefixes.

Kernel type	Writing
Webkit(Chrome/Safari)	-webkit-transform
Gecko(Firefox)	-moz-transform
Presto(Opera)	-o-transform
Trident(IE)	-ms-transform
W3C	transform

Example:
