2.3.9 Nested Views Codehs (Mobile)

Ensure you explicitly set whether a container stacks its children vertically or horizontally. Forgetting to set this property causes elements to default to standard stacking, breaking the layout.

components placed inside the parent. Their size can be controlled using fixed Flexbox Styling

As you move past section 2.3.9 into more advanced CodeHS modules, keeping your UI code clean is paramount:

Without nesting, aligning multiple elements on a small mobile screen becomes chaotic. Nesting allows you to:

: Remember that flex: 1 on a nested view tells it to take up all available space within its parent , not the whole screen. Their size can be controlled using fixed Flexbox

Finally, place your text, buttons, or images inside the innermost nested views. Visualizing the Code Structure
