# background(_:in:fillStyle:) Sets the view’s background to an insettable shape filled with a style. ``` nonisolated func background(_ style: S, in shape: T, fillStyle: FillStyle = FillStyle()) -> some View where S : ShapeStyle, T : InsettableShape ``` ## Parameters `style` A [`ShapeStyle`](/documentation/SwiftUI/ShapeStyle) that SwiftUI uses to the fill the shape that you specify. `shape` An instance of a type that conforms to [`InsettableShape`](/documentation/SwiftUI/InsettableShape) that SwiftUI draws behind the view. `fillStyle` The [`FillStyle`](/documentation/SwiftUI/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 insettable shape drawn behind it. ## Discussion Use this modifier to layer a type that conforms to the [`InsettableShape`](/documentation/SwiftUI/InsettableShape) protocol — like a [`Rectangle`](/documentation/SwiftUI/Rectangle), [`Circle`](/documentation/SwiftUI/Circle), or [`Capsule`](/documentation/SwiftUI/Capsule) — behind a view. Specify the [`ShapeStyle`](/documentation/SwiftUI/ShapeStyle) that’s used to fill the shape. For example, you can place a [`RoundedRectangle`](/documentation/SwiftUI/RoundedRectangle) behind a [`Label`](/documentation/SwiftUI/Label): ``` Label("Flag", systemImage: "flag.fill") .padding() .background(.teal, in: RoundedRectangle(cornerRadius: 8)) ``` The [`teal`](/documentation/SwiftUI/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`](/documentation/SwiftUI/View) types — or with a stack of views — use [`background(alignment:content:)`](/documentation/SwiftUI/View/background(alignment:content:)) instead. To add a [`ShapeStyle`](/documentation/SwiftUI/ShapeStyle) as a background, use [`background(_:ignoresSafeAreaEdges:)`](/documentation/SwiftUI/View/background(_:ignoresSafeAreaEdges:)). --- Copyright © 2026 Apple Inc.
