The CodeHS introduces foundational UI/UX concepts using React Native. Within this curriculum, Exercise 2.3.9: Nested Views is a key milestone for mastering component layout, Flexbox properties, and nested hierarchies. Core Concepts of Nested Views
Aligns child components along the cross axis (perpendicular to the primary axis). 2.3.9 nested views codehs
Remember that changing the flexDirection flips the axes. When flexDirection: 'row' is applied, justifyContent controls horizontal alignment, and alignItems controls vertical alignment. Remember that changing the flexDirection flips the axes
import React from 'react'; import { StyleSheet, View } from 'react-native'; export default function App() { return ( // Root Container {/* Outer Box (Parent) */} {/* Inner Box 1 (Child) */} {/* Nested Grandchild */} {/* Inner Box 2 (Child) */} ); } const styles = StyleSheet.create({ container: { flex: 1, backgroundColor: '#fff', alignItems: 'center', justifyContent: 'center', }, outerBox: { width: 300, height: 300, backgroundColor: '#2ecc71', // Emerald Green flexDirection: 'row', justifyContent: 'space-around', alignItems: 'center', }, innerBoxOne: { width: 100, height: 100, backgroundColor: '#3498db', // Blue justifyContent: 'center', alignItems: 'center', }, innerBoxTwo: { width: 100, height: 100, backgroundColor: '#e74c3c', // Red }, grandChildBox: { width: 40, height: 40, backgroundColor: '#f1c40f', // Yellow }, }); Use code with caution. Step-by-Step Implementation Breakdown justifyContent controls horizontal alignment
Serves as the container. It uses Flexbox properties to dictate the alignment and distribution of its children.
