Styling

Styling is a Angular topic. In plain words you use it for red Fail / green Pass in the mark sheet. Don’t start with a slogan — start with that picture.

Smallest example: [ngClass] or [style.color]. Type it, run it, and say what you see. If you can do that from memory, you know Styling.

From the example next to this theory — Styling: toggle open.

Trap — hard-coding colour in TS only. Fix that before you talk about advanced Angular.

Viva — what is Styling? Then show [ngClass] or [style.color]. Then name the trap.

Exam tip

What is Styling? Show this: [ngClass] or [style.color]. Trap: hard-coding colour in TS only.

Example

import { Component } from "@angular/core";

@Component({
  selector: "app-root",
  template: `
    <h1>{{ title }}</h1>
    <button (click)="toggle()">Toggle</button>
    <p *ngIf="open">Panel open</p>
  `,
})
export class AppComponent {
  title = "Angular practice";
  open = true;
  toggle() {
    this.open = !this.open;
  }
}

Styling: toggle open. Say whether the panel is on screen after one click.
