# HStack

A SwiftUI HStack component for horizontal layouts.
iOS, tvOS

> For the complete documentation index, see [llms.txt](/llms.txt). Use this file to discover all available pages.

Expo UI HStack matches the official SwiftUI [HStack API](https://developer.apple.com/documentation/swiftui/hstack) and arranges its children horizontally.

## Installation

```sh
npx expo install @expo/ui
```

If you are installing this in an [existing React Native app](/bare/overview), make sure to [install `expo`](/bare/installing-expo-modules) in your project.

## Usage

### Basic horizontal stack

```tsx
import { Host, HStack, Text } from '@expo/ui/swift-ui';

export default function BasicHStackExample() {
  return (
    <Host matchContents>
      <HStack spacing={12}>
        <Text>First</Text>
        <Text>Second</Text>
        <Text>Third</Text>
      </HStack>
    </Host>
  );
}
```

### With alignment

The `alignment` prop controls vertical alignment of children. Available options are: `top`, `center`, `bottom`, `firstTextBaseline`, and `lastTextBaseline`.

```tsx
import { Host, HStack, Rectangle } from '@expo/ui/swift-ui';
import { frame } from '@expo/ui/swift-ui/modifiers';

export default function HStackAlignmentExample() {
  return (
    <Host matchContents>
      <HStack spacing={12} alignment="top">
        <Rectangle modifiers={[frame({ width: 50, height: 50 })]} />
        <Rectangle modifiers={[frame({ width: 50, height: 100 })]} />
        <Rectangle modifiers={[frame({ width: 50, height: 75 })]} />
      </HStack>
    </Host>
