Angular Animations: Smooth UI Transitions

Animations improve user experience when used with purpose, like: - dropdown open/close - accordion expand - page transition ## Step 1: Install animations module (if needed) In modern Angular, ensure animations are enabled via providers: `provideAnimations()` ## Step 2: Basic fade animation ```ts import { Component } from '@angular/core'; import { trigger, transition, style, animate } from '@angular/animations'; @Component({ selector: 'app-fade', standalone: true, animations: [ trigger('fade', [ transition(':enter', [ style({ opacity: 0 }), animate('200ms', style({ opacity: 1 })), ]), transition(':leave', [ animate('200ms', style({ opacity: 0 })), ]), ]), ], template: ` <button (click)="toggle()">Toggle</button> <p *ngIf="show" @fade>Now you see me</p> `, }) export class FadeComponent { show = true; toggle() { this.show = !this.show; } } ``` ## Keep animations professional - fast and subtle - do not animate everything - prefer simple transitions > Next: Internationalization (i18n) and localization patterns.
