![]() Doesn't enforce any layout constraints on its children.Uses a pair of absolute left/top coordinates to position its children.The container is the simplest layout container in NativeScript. All other components are considered content that should be constrained to the safe area and default to false. The default value for container components is true. Set it to false to explicitly prevent this behavior. Set this property value to true if you want the component to expand to the edges of the screen when it borders the safe area. Additionally, NativeScript 5.0 exposes a property iosOverflowSafeArea that can control how components handle the iOS Safe Area. The above default behavior should provide good UX out of the box. You can prevent this behavior by setting the iosOverflowSafeArea property below to false. The above workflow can lead to containers being laid out with a bigger size than initially declared in the markup. Layout pass - if the component borders the safe area, it is adjusted and expanded to the edges of the screen.Layout pass - all components are laid out in full screen, but are inset to the safe area boundaries.Measure pass - all components are measured in the safe area portion of the screen.The default behavior is that certain container View components (these that can have children) overflow the safe area and are laid out to the edges of the screen. Since version 5.0 NativeScript provides a default handling mechanism for the iOS Safe Area. To get a better understanding refer to the Apple docs. It is affected by the notch, the rounded corners of the screen, the status bar and the home indicator, but also from parts of your application like the action bar and the tab bar. It is the area of the screen that is free to use and won’t be obstructed by hardware and software parts of the system. The iOS Safe Area is a term that Apple introduced in iOS 11. For example, if you set marginLeft='5%', the element will have a margin that corresponds to 5% of the parent's available width. This means that on vertical StackLayout if you place two Buttons with height='50%' they will get all the available height (e.g., they will fill the StackLayout vertically.). When a layout pass begins, first the percent values are calculated based on parent available size. NativeScript supports percentage values for width, height and margin. The view is stretched to fill the layout slot of the parent element height takes precedence, if set. The view is aligned to the bottom of the layout slot of the parent element. The view is aligned to the top of the layout slot of the parent element. ![]() The following table shows the valid values of verticalAlignment. The view is stretched to fill the layout slot of the parent element width takes precedence, if set. The view is aligned to the right of the layout slot of the parent element. The view is aligned to the center of the layout slot of the parent element. The view is aligned to the left of the layout slot of the parent element. The following table shows the valid values of horizontalAlignment. Layout applies horizontal and vertical alignment only when an element is allocated more size than it needs. The first value is applied to the top, the second value is applied to the right, the third value is applied to the bottom and the fourth value is applied to the left side (in that order). Set four values: Provide four values for each padding.When you set paddings through XML, you can choose between the following approaches. The four padding properties ( paddingTop, paddingRight, paddingBottom and paddingLeft) describe the distance between the layout container and its children. Set four values: Provide four values for each margin.Next, the first value is applied to the bottom and the second value to the left side (in that order). The first value is applied to the top side, the second value is applied to the right side. Set one value: Provide a single value that will be applied on all sides of the view.When you set margins through XML, you can choose between the following approaches. ![]() The four margin properties ( marginTop, marginRight, marginBottom and marginLeft) describe the distance between a view and its parent.
