How to rotate css

In css, you can use the transform attribute to achieve element rotation. When the value is set to "rotate (angle)", 2D rotation can be achieved; when the value is "rotateX (angle)", it can be rotated along the X axis, and "rotateY" (angle)" can be rotated along the Y axis, and "rotateZ(angle)" can be rotated along the Z axis.

The operating environment of this tutorial: Windows 7 system, CSS3&&HTML5 version, Dell G3 computer.

TheTransform property applies a 2D or 3D transformation to the element. This property allows you to rotate, scale, move, tilt, etc. the element. The

Transform attribute has 5 attribute values ​​for setting translation:

• rotate(angle) defines 2D rotation and specifies the angle in the parameters.

• rotate3d(x,y,z,angle) Define 3D rotation.

• rotateX(angle) Defines a 3D rotation along the X-axis.

• rotateY(angle) Defines 3D rotation along the Y axis.

• rotateZ(angle) Defines 3D rotation along the Z axis.
