Every opening tag must have a matching closing tag. A missing or will cause a syntax compilation error. Incorrect: Hello Correct: Hello 2. Forgetting to Import Components

Option A: Relative Positioning (Modern UI libraries)

Every opening must have a matching closing . If you nest deeply, it is easy to forget a closing tag or close them in the wrong order.

components within one another using React Native. This exercise follows basic layout principles like alignItems justifyContent to create a visual hierarchy. Create an app that contains a main parent with at least two internal nested

Remember that styling properties are not automatically inherited by child views. If you want a nested view to center its internal items, you must explicitly add justifyContent: 'center' and alignItems: 'center' directly to that nested view's style object. 2.3.9 nested views codehs

export const styles = StyleSheet.create( container: flex: 1, justifyContent: 'center', alignItems: 'center', , viewOne: width: 250, height: 250, backgroundColor: 'powderblue', justifyContent: 'center', // To center the inner View alignItems: 'center', , viewTwo: width: 150, height: 150, backgroundColor: 'skyblue', justifyContent: 'center', alignItems: 'center', , viewThree: width: 75, height: 75, backgroundColor: 'steelblue', justifyContent: 'center', alignItems: 'center', , );

Below is a clean, standard architectural template demonstrating how to properly nest components and apply styles using JavaScript/React Native principles. The Layout Architecture Use code with caution. Common Mistakes and How to Debug Them

If your components are stacking vertically when they should be side-by-side, verify that the parent view has flexDirection: 'row' explicitly defined.

function Sidebar() return <aside>Sidebar content</aside>; Every opening tag must have a matching closing tag

.outer-container width: 80%; margin: auto; border: 2px solid black; padding: 10px;

If you get stuck, remember to check the CodeHS documentation tab within the editor, which provides helpful syntax reminders and examples. Good luck, and happy coding!

To solve the nested views exercise, you need to structure your JavaScript/React Native code to have a "wrapper" view and internal "inner" views. 1. The Structure Holds everything.

: The outermost container that holds all other elements. It usually requires to fill the entire screen. Child Views function Sidebar() return &lt

Children inherit positioning attributes from their parent. Understanding the CodeHS 2.3.9 Exercise Context

Remember that flex: 1 tells a child view to expand and fill all available space within its parent. If the parent doesn't have a defined height or flex , the child might "disappear."

If Child A has flex: 1 and Child B has flex: 2 , the parent space is divided into 3 equal parts. Child B will occupy of the screen, while Child A takes one-third . Step-by-Step Code Structure for 2.3.9
