Angular PrimeNG Skeleton Animation

Angular PrimeNG is an open-source framework with a rich set of native Angular UI components that are used for great styling and this framework is used to make responsive websites with very much ease. In this article, we will know how to use Skeleton Animation in Angular PrimeNG. We will also learn about the properties along with their syntaxes that will be used in the code.

The Skeleton component serves as a stand-in for the material to be shown. The animation can be removed from the skeleton elements using the animation=”none” property.

Example 1: Below is the example code that illustrates the use of Angular PrimeNG Skeleton Animation using the Square and Circle Skeleton.

app.component.html

<h2 style="color: green;">GeeksforGeeks</h2>
<h5>Angular PrimeNG Skeleton Animation</h5>

<div class="p-d-flex">
    <div>
        Square with animation
        <p-skeleton

                size="10rem"
                styleClass="p-mr-3 p-mt-2">
        </p-skeleton>
    </div>

    <div>
        Circle with animation
        <p-skeleton
                shape="circle"
                size="10rem"
                styleClass="p-mr-3 p-mt-2">
        </p-skeleton>
    </div>
</div>

app.component.ts

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

import { ButtonModule } from 'primeng/button';
import { BadgeModule } from 'primeng/badge';
import { SkeletonModule } from 'primeng/skeleton';
import { TableModule } from 'primeng/table';

      ButtonModule,
      TableModule,
      BadgeModule,
   ],
   declarations: [AppComponent],

export class AppModule {}

Output:
