# init(horizontal:vertical:) Creates a custom alignment value with the specified horizontal and vertical alignment guides. ``` init(horizontal: HorizontalAlignment, vertical: VerticalAlignment) ``` ## Parameters `horizontal` The alignment on the horizontal axis. `vertical` The alignment on the vertical axis. ## Discussion SwiftUI provides a variety of built-in alignments that combine built-in [`HorizontalAlignment`](/documentation/SwiftUI/HorizontalAlignment) and [`VerticalAlignment`](/documentation/SwiftUI/VerticalAlignment) guides. Use this initializer to create a custom alignment that makes use of a custom horizontal or vertical guide, or both. For example, you can combine a custom vertical guide called `firstThird` with the built-in [`center`](/documentation/SwiftUI/HorizontalAlignment/center) guide, and use it to configure a [`ZStack`](/documentation/SwiftUI/ZStack): ``` ZStack(alignment: Alignment(horizontal: .center, vertical: .firstThird)) { // ... } ``` For more information about creating custom guides, including the code that creates the custom `firstThird` alignment in the example above, see [`AlignmentID`](/documentation/SwiftUI/AlignmentID). --- Copyright © 2026 Apple Inc.
