Example 1: Below is the example code that illustrates the use of the Angular PrimeNG Styling for the Messages Component. In the following example, we have a Messages component with a border along the messages.

app.component.html:

HTML

<h1 style="color: green; text-align: center;">
    GeeksforGeeks
</h1>
<h3>Angular PrimeNG Styling for Messages Component</h3>

<p-button type="button" 
    (click)="showViaService()">
      Show
</p-button>
<p-button type="button" 
    (click)="clear()">
      Hide
</p-button>
<p-messages [(value)]="msgs"></p-messages>

app.component.css:

CSS

:host ::ng-deep .p-messages {
    border: solid #8a427a;
    border-width: 6px;
    color: #2c1e30;
    padding: 12px;
}

app.component.ts:

JavaScript

import { Component } from "@angular/core";
import { PrimeNGConfig } from "primeng/api";
import { MessageService } from "primeng/api";

@Component({
    selector: "app-root",
    templateUrl: "./app.component.html",
    styleUrls: ["./app.component.css"],
    providers: [MessageService]
})

export class AppComponent {
    constructor(private messageService: MessageService) {}

    ngOnInit() {}

    clear() {
        this.messageService.clear();
    }
    showViaService() {
        this.messageService.add({
            severity: "success",
            summary: "GeeksforGeeks",
            detail: "Welcome to GeeksforGeeks"
        });
    }
}

app.module.ts:

JavaScript

import { NgModule } from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { FormsModule } from "@angular/forms";
import { BrowserAnimationsModule } 
    from "@angular/platform-browser/animations";
import { AppComponent } from "./app.component";
import { CarouselModule } from "primeng/carousel";
import { ButtonModule } from "primeng/button";
import { ImageModule } from "primeng/image";
import { MessagesModule } from "primeng/messages";
import { MessageModule } from "primeng/message";
@NgModule({
    imports: [
        BrowserModule,
        BrowserAnimationsModule,
        CarouselModule,
        ButtonModule,
        FormsModule,
        ImageModule,
        MessageModule,
        MessagesModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})

export class AppModule {}

Output:

Example 2: Below is another example code in which we will apply shadow to individual messages.

app.component.html:

HTML

    GeeksforGeeks
</h1>
<h3>Angular PrimeNG Styling for Messages Component</h3>

<p-button type="button" 
    (click)="showViaService()">

    (click)="clear()">
      Hide
</p-button>
<p-messages [(value)]="msgs"></p-messages>

app.component.css:

CSS

:host ::ng-deep .p-message {
    box-shadow: 1px 1px 2px black, 0 0 25px rgb(9, 255, 71),
        0 0 5px rgb(0, 58, 17);
}

app.component.ts:

JavaScript

import { PrimeNGConfig } from "primeng/api";
import { MessageService } from "primeng/api";

@Component({
    selector: "app-root",
    templateUrl: "./app.component.html",
    styleUrls: ["./app.component.css"],
    providers: [MessageService]
})

export class AppComponent {
    constructor(private messageService: MessageService) {}

    ngOnInit() {}

    clear() {
        this.messageService.clear();
    }
    showViaService() {
        this.messageService.add({
            severity: "success",
            summary: "GeeksforGeeks",
            detail: "Welcome to GeeksforGeeks"
        });
    }
}

app.module.ts:

JavaScript

import { NgModule } from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { FormsModule } from "@angular/forms";
import { BrowserAnimationsModule } 
    from "@angular/platform-browser/animations";
import { AppComponent } from "./app.component";
import { CarouselModule } from "primeng/carousel";
import { ButtonModule } from "primeng/button";
import { ImageModule } from "primeng/image";
import { MessagesModule } from "primeng/messages";
