# translateZ()

The `translateZ()` CSS function repositions an element along the z-axis in 3D space, i.e., closer to or farther away from the viewer. Its result is a `<transform-function>` data type.

This transformation is defined by a `<length>` which specifies how far inward or outward the element or elements move.

In the above interactive examples, `perspective: 550px;` (to create a 3D space) and `transform-style: preserve-3d;` (so the children, the 6 sides of the cube, are also positioned in the 3D space), have been set on the cube.

Note: `translateZ(tz)` is equivalent to `translate3d(0, 0, tz)`.

## Syntax

```translateZ(tz)
```

### Values

`tz`
A `<length>` representing the z-component of the translating vector. A positive value moves the element towards the viewer, and a negative value farther away.
Cartesian coordinates on ℝ2 Homogeneous coordinates on ℝℙ2 Cartesian coordinates on ℝ3 Homogeneous coordinates on ℝℙ3
This transformation applies to the 3D space and can't be represented on the plane. A translation is not a linear transformation in ℝ3 and can't be represented using a Cartesian-coordinate matrix. $\left(\begin{array}{ccc}10& 0& 0\\ 01& 0& 0\\ 0& 0& 1& t\\ 0& 0& 0& 1\end{array}\right)$

## Examples

In this example, two boxes are created. One is positioned normally on the page, without being translated at all. The second is altered by applying perspective to create a 3D space, then moved towards the user.

### HTML

```<div>Static</div>
<div class="moved">Moved</div>```

### CSS

```div {
position: relative;
width: 60px;
height: 60px;
left: 100px;
background-color: skyblue;
}

.moved {
transform: perspective(500px) translateZ(200px);
background-color: pink;
}
```

What really matters here is the class "moved"; let's take a look at what it does. First, the `perspective()` function positions the viewer relative to the plane that lies where z=0 (in essence, the surface of the screen). A value of `500px` means the user is 500 pixels "in front of" the imagery located at z=0.

Then, the `translateZ()` function moves the element 200 pixels "outward" from the screen, toward the user. This has the effect of making the element appear larger when viewed on a 2D display, or closer when viewed using a VR headset or other 3D display device.

Note if the `perspective()` value is less than the `translateZ()` value, such as `transform: perspective(200px) translateZ(300px);` the transformed element will not be visible as it is further than the user's viewport. The smaller the difference between the perspective and translateZ values, the closer the user is to the element and the larger the translated element will seem.
