Web Components Barra de navegación

La barra de navegación Ignite UI for Web Components informa al usuario de su posición actual en una aplicación. La barra de navegación también puede proporcionar enlaces a acciones rápidas como la búsqueda o el favorito, lo que ayuda a los usuarios a navegar sin problemas por una aplicación sin intentar pasar a rutas o estados no válidos. La barra se encuentra en la parte superior del recipiente en el que se coloca.

El siguiente ejemplo representa un IgcNavbarComponent con iconos y encabezado de texto:

import { defineComponents, IgcNavbarComponent, IgcIconComponent, registerIconFromText } from 'igniteui-webcomponents';
import 'igniteui-webcomponents/themes/light/bootstrap.css';

defineComponents(IgcNavbarComponent, IgcIconComponent);
export class NavbarOverview {

Styling

El NavBar componente expone varias partes CSS, lo que le proporciona un control total sobre su estilo:

Nombre	Descripción
`base`	El contenedor base de la barra de navegación.
`start`	El contenedor de iconos alineado a la izquierda.
`middle`	El contenedor de título de la barra de navegación.
`end`	El contenedor de iconos de acción alineados a la derecha.

igc-icon {
  color: var(--ig-primary-500);
}

igc-navbar {
  background-color: var(--ig-secondary-200);
}

igc-navbar::part(middle) {
  font-family: Titillium Web, sans-serif;
  color: var(--ig-primary-500);;
}
css

Si todo ha ido bien deberías ver lo siguiente en tu navegador:

import { defineComponents, IgcNavbarComponent, IgcIconComponent, registerIconFromText } from 'igniteui-webcomponents';
