|---|---|
| `https://developer.android.com/reference/kotlin/androidx/compose/ui/BiasAbsoluteAlignment.Horizontal` | An `https://developer.android.com/reference/kotlin/androidx/compose/ui/Alignment.Horizontal` specified by bias: for example, a bias of -1 represents alignment to the left, a bias of 0 will represent centering, and a bias of 1 will represent right. |

*** ** * ** ***

An interface to calculate the position of box of a certain width inside an available width. `https://developer.android.com/reference/kotlin/androidx/compose/ui/Alignment.Horizontal` is often used to define the horizontal alignment of a layout inside a parent layout.

## Public functions

### align

Cmn Added in [1.0.0](https://developer.android.com/jetpack/androidx/releases/compose-ui#1.0.0)

```
fun align(size: Int, space: Int, layoutDirection: LayoutDirection): Int
```

Calculates the horizontal position of a box of width `https://developer.android.com/reference/kotlin/androidx/compose/ui/Alignment.Horizontal#align(kotlin.Int,kotlin.Int,androidx.compose.ui.unit.LayoutDirection)` relative to the left side of an area of width `https://developer.android.com/reference/kotlin/androidx/compose/ui/Alignment.Horizontal#align(kotlin.Int,kotlin.Int,androidx.compose.ui.unit.LayoutDirection)`. The returned offset can be negative or larger than `space - size` meaning that the box will be positioned partially or completely outside the area.

### plus

Cmn Added in [1.8.0](https://developer.android.com/jetpack/androidx/releases/compose-ui#1.8.0)

```
open operator fun plus(other: Alignment.Vertical): Alignment
```

Combine this instance's horizontal alignment with `https://developer.android.com/reference/kotlin/androidx/compose/ui/Alignment.Horizontal#plus(androidx.compose.ui.Alignment.Vertical)`'s vertical alignment to create an `https://developer.android.com/reference/kotlin/androidx/compose/ui/Alignment`.
