# translateY()

The `translateY()` CSS function repositions an element vertically on the 2D plane. Its result is a `<transform-function>` data type.

Note: `translateY(ty)` is equivalent to `translate(0, ty)` or `translate3d(0, ty, 0)`.

## Syntax

```/* <length-percentage> values */
transform: translateY(200px);
transform: translateY(50%);
```

### Values

`<length-percentage>`
The value is a `<length>` or `<percentage>` representing the ordinate of the translating vector. A percentage value refers to the height of the reference box defined by the `transform-box` property.
Cartesian coordinates on ℝ2 Homogeneous coordinates on ℝℙ2 Cartesian coordinates on ℝ3 Homogeneous coordinates on ℝℙ3

A translation is not a linear transformation in ℝ2 and can't be represented using a Cartesian-coordinate matrix.

$\left(\begin{array}{cc}10& 0\\ 01& t\\ 0& 0& 1\end{array}\right)$ $\left(\begin{array}{cc}10& 0\\ 01& t\\ 0& 0& 1\end{array}\right)$ $\left(\begin{array}{ccc}10& 0& 0\\ 01& 0& t\\ 0& 0& 1& 0\\ 0& 0& 0& 1\end{array}\right)$
`[1 0 0 1 0 t]`

### Formal syntax

```translateY(`<length-percentage>`)
```
