Angular - Components

Given this Angular component code:

@Component({
  selector: 'app-box',
  template: `Hello`,
  styles: [`.box { color: red; }`],
  encapsulation: ViewEncapsulation.None
})
export class BoxComponent {}

What will be the color of all elements with class box in the entire app?

AAll <code>box</code> elements in the app will be red.

BOnly the <code>box</code> inside <code>app-box</code> will be red.

CNo <code>box</code> elements will be red because styles are scoped.

DOnly <code>box</code> elements inside Shadow DOM will be red.

Step-by-Step Solution

Solution:

Step 1: Understand ViewEncapsulation.None effect
None disables style encapsulation, so styles apply globally to all matching elements.
Step 2: Apply to the .box class
The style `.box { color: red; }` will affect every element with class 'box' in the entire app, not just inside this component.
Final Answer:
All box elements in the app will be red. -> Option A
Quick Check:
None encapsulation = global styles [OK]

Quick Trick: None means styles leak globally, coloring all matching elements [OK]

Common Mistakes:

Assuming styles stay inside component with None
Confusing ShadowDom encapsulation effects
Thinking Emulated behaves like None
