# background(_:in:fillStyle:) Sets the view’s background to a shape filled with a style. ``` nonisolated func background(_ style: S, in shape: T, fillStyle: FillStyle = FillStyle()) -> some View where S : ShapeStyle, T : Shape ``` ## Parameters `style` A `ShapeStyle` that SwiftUI uses to the fill the shape that you specify. `shape` An instance of a type that conforms to `Shape` that SwiftUI draws behind the view. `fillStyle` The `FillStyle` to use when drawing the shape. The default style uses the nonzero winding number rule and antialiasing. ## Return Value A view with the specified shape drawn behind it. ## Discussion Use this modifier to layer a type that conforms to the `Shape` protocol behind a view. Specify the `ShapeStyle` that’s used to fill the shape. For example, you can create a `Path` that outlines a trapezoid: ``` let trapezoid = Path { path in path.move(to: .zero) path.addLine(to: CGPoint(x: 90, y: 0)) path.addLine(to: CGPoint(x: 80, y: 50)) path.addLine(to: CGPoint(x: 10, y: 50)) } ``` Then you can use that shape as a background for a `Label`: ``` Label("Flag", systemImage: "flag.fill") .padding() .background(.teal, in: trapezoid) ``` The `ShapeStyle/teal` color fills the shape:  This modifier is a convenience method for placing a single shape behind a view. To create a background with other `View` types — or with a stack of views — use `View/background(alignment:content:)` instead. To add a `ShapeStyle` as a background, use `View/background(_:ignoresSafeAreaEdges:)`. --- Copyright © 2026 Apple Inc.
