# CSS rotateY() Function – How to Rotate Elements around Y-axis

rotateY() transforms an element by rotating it three-dimensionally around the Y-axis. A three-dimensional Cartesian coordinate system showing the X-, Y-, and Z-axis

## Syntax of the CSS rotateY() Function​

rotateY() accepts a single argument. Here is the syntax:

element {  transform: rotateY(angle);}

Note the following:

• The rotateY(angle) function is equivalent to rotate3d(0, 1, 0, angle).
• The angle argument specifies the element's angle of rotation.
• angle can be in degree, gradian, radian, or turn.
• An angle argument consists of a number followed by the unit you wish to use—for instance, 45deg.

## Examples of the CSS rotateY() Function​

Below are some examples of how the CSS rotateY() function works.

### How to do a zero-degree rotation around the Y-axis​

img {  transform: rotateY(0deg);  width: 80%;}

The snippet above used the rotateY() function to specify a zero-degree (0⁰) rotation for the image around the Y-axis.

### How to do a 70-degree rotation around the Y-axis​

img {  transform: rotateY(70deg);  width: 80%;}

The snippet above used the rotateY() function to specify a seventy-degree (70⁰) rotation for the image around the Y-axis.

## CSS rotateY() Function vs. rotate Property: What's the Difference?​

CSS rotateY() functions and CSS rotate property provide two similar ways to specify rotation transformations.

The main differences between the two rotation techniques are as follows:

• The CSS rotate property allows rotating an element without using the CSS transform property.
• The CSS rotate property's syntax is shorter than its function alternative.
• The CSS rotate property saves you from remembering the specific order to position the transform functions.
• Browsers calculate the transform functions' matrix in the order you assigned them to the CSS transform property—from left to right.
• Browsers calculate the transform properties' matrix in the following transformation matrix order:
1. translate
2. rotate
3. scale

Here's an example:

Use CSS rotate property to do a 70-degree rotation around the Y-axis:

img {  rotate: y 70deg; /* Equal to a transform: rotateY(70deg) property */  width: 80%;}

The snippet above used the rotate property to specify a seventy-degree (70⁰) rotation for the image around the Y-axis.

note

A none value tells browsers not to rotate the selected element.
