struct ContentView: View {
    @State private var text = ""

    var body: some View {
        GeometryReader { geometry in
            VStack {
                TextField("Enter text", text: $text)
                    .frame(height: 40)
                    .background(Color.gray.opacity(0.2))
                    .cornerRadius(10)
                    .padding(.all, 20)

                Spacer()
            }
            .frame(width: geometry.size.width, height: geometry.size.height)
            .background(Color.white)
            .cornerRadius(20)
            .padding(.bottom, geometry.safeAreaInsets.bottom + 20) // Adjust padding based on safe area
        }
    }
}

struct ContentView: View {
    var body: some View {
        ZStack {
            Color.blue
                .ignoresSafeArea() // Only the blue background ignores safe area

            VStack {
                Text("Hello, World!")
                    .padding(.all, 20)
