+    - `bg-transparent`: Fondo transparente para que se vea el color de fondo de tu web.
+    - `border-b-2`: Borde solo abajo (estilo línea).
+    - `focus:ring-0`: Quita el anillo azul de Chrome al hacer click.
+    - `peer`: Permite que el icono de la flecha cambie de color cuando el select tiene foco.
