CSS3 allows you to format HTML elements using 3D transformations. 3D transformation methods are:
1. rotateX()
2. rotateY()
3. rotateZ()

The rotateX() Method

The rotateX() method rotates an element around its X-axis (vertically) at a given degree:
Syntax: transform: rotateX(150deg);

The rotateY() Method

The rotateY() method rotates an element around its Y-axis (Horizontally) at a given degree:
Syntax: transform: rotateY(130deg);

The rotateZ() Method

The rotateZ() method rotates an element around its Z-axis at a given degree:
Syntax: transform: rotateZ(90deg);
