# translateX()

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

Note: `translateX(tx)` is equivalent to `translate(tx, 0)` or `translate3d(tx, 0, 0)`.

## Syntax

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

### Values

`<length-percentage>`
Is a `<length>` or `<percentage>` representing the abscissa of the translating vector. A percentage value refers to the width 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.

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

### Formal syntax

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

## Examples

### HTML

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

### CSS

```div {
width: 60px;
