```kotlin
public fun slideInHorizontally(
    animationSpec: FiniteAnimationSpec<IntOffset> =
        spring(
            stiffness = Spring.StiffnessMediumLow,
            visibilityThreshold = IntOffset.VisibilityThreshold,
        ),
    initialOffsetX: (fullWidth: Int) -> Int = { -it / 2 },
): EnterTransition
```

This slides in the content horizontally, from a starting offset defined in `initialOffsetX` to
`0` **pixels**. The direction of the slide can be controlled by configuring the `initialOffsetX`.
A positive value means sliding from right to left, whereas a negative value would slide the
content from left to right.

`initialOffsetX` is a lambda that takes the full width of the content and returns an offset. This
allows the starting offset to be defined proportional to the full size, or as an absolute value.
It defaults to return half of negative width, which would offset the content to the left by half
of its width, and slide towards the right.

#### Parameters

| | |
| --- | --- |
| animationSpec | the animation used for the slide-in, [spring](/jetpack-compose/androidx.compose.animation/animation-core/functions/spring) by default. |
| initialOffsetX | a lambda that takes the full width of the content in pixels and returns the initial offset for the slide-in, by default it returns `-fullWidth/2` |
