With CSS3 transform, we can move, scale, turn, spin, and stretch elements.
A transformation is an effect that lets an element change shape, size and position.
You can transform your elements using 2D or 3D transformation.
The numbers in the table specify the first browser version that fully supports the property.
Numbers followed by -ms-, -webkit-, -moz-, or -o- specify the first version that worked with a prefix.

In this chapter you will learn about the 2d transform methods:
You will learn about 3D transforms in the next chapter.
With the translate() method, the element moves from its current position, depending on the parameters given for the left (X-axis) and the top (Y-axis) position:
The value translate(50px,100px) moves the element 50 pixels from the left, and 100 pixels from the top.
With the rotate() method, the element rotates clockwise at a given degree. Negative values are allowed and rotates the element counter-clockwise.
The value rotate(30deg) rotates the element clockwise 30 degrees.
With the scale() method, the element increases or decreases the size, depending on the parameters given for the width (X-axis) and the height (Y-axis):
The value scale(2,4) transforms the width to be twice its original size, and the height 4 times its original size.
With the skew() method, the element turns in a given angle, depending on the parameters given for the horizontal (X-axis) and the vertical (Y-axis) lines:
The value skew(30deg,20deg) turns the element 30 degrees around the X-axis, and 20 degrees around the Y-axis.
The matrix() method combines all of the 2D transform methods into one.
The matrix method take six parameters, containing mathematic functions, which allows you to: rotate, scale, move (translate), and skew elements.

The following table lists all the transform properties:
| Property | Description |
|---|---|
| transform | Applies a 2D or 3D transformation to an element |
| transform-origin | Allows you to change the position on transformed elements |
| Function | Description |
|---|---|
| matrix(n,n,n,n,n,n) | Defines a 2D transformation, using a matrix of six values |
| translate(x,y) | Defines a 2D translation, moving the element along the X- and the Y-axis |
| translateX(n) | Defines a 2D translation, moving the element along the X-axis |
| translateY(n) | Defines a 2D translation, moving the element along the Y-axis |
| scale(x,y) | Defines a 2D scale transformation, changing the elements width and height |
| scaleX(n) | Defines a 2D scale transformation, changing the element's width |
| scaleY(n) | Defines a 2D scale transformation, changing the element's height |
| rotate(angle) | Defines a 2D rotation, the angle is specified in the parameter |
| skew(x-angle,y-angle) | Defines a 2D skew transformation along the X- and the Y-axis |
| skewX(angle) | Defines a 2D skew transformation along the X-axis |
| skewY(angle) | Defines a 2D skew transformation along the Y-axis |
