Bootstrap 4 - Breadcrumb
Descripción
Se utiliza para mostrar información basada en la jerarquía de un sitio e indica la ubicación de la página actual dentro de una jerarquía de navegación. Bootstrap usa la clase .breadcrumb para definir la lista en migas de pan y agrega un separador a través de CSS a la lista.
El siguiente ejemplo demuestra esto:
Ejemplo
<html lang = "en">
<head>
<!-- Meta tags -->
<meta charset = "utf-8">
<meta name = "viewport" content = "width = device-width, initial-scale = 1, shrink-to-fit = no">
<!-- Bootstrap CSS -->
<link rel = "stylesheet"
href = "https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css"
integrity = "sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO"
