Here is an example of how you can create a navigation bar in Angular:

First, you will need to create a component for the navigation bar. In the component’s template, you can use the <nav> element to define the navigation bar. You can then use the <a> element to create the links for the navigation bar.

Here is an example of a navigation bar component:

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

@Component({
    selector: 'app-navbar',
    template: `
    <nav>
      <a routerLink="/home">Home</a>
      <a routerLink="/about">About</a>
      <a routerLink="/contact">Contact</a>
    </nav>
  `,
    styles: [`
    nav {
      display: flex;
      justify-content: space-around;
    }
    a {
      color: white;
      text-decoration: none;
      padding: 1em;
      display: block;
    }
  `]
})
export class NavbarComponent {
}

To use the navigation bar component in your app, you will need to add it to the declarations array in the module where it will be used. Then, you can use the <app-navbar> element in the template of any component to display the navigation bar.

Here is an example of how you can use the navigation bar component in a component template:

<app-navbar></app-navbar>
<router-outlet></router-outlet>

This will display the navigation bar at the top of the component, and the router-outlet element will display the content for the selected route.
