Quiero agregar un pie de página y un encabezado a mi tarea de látex. Y uso el siguiente código:
\documentclass{article}
\usepackage[english]{babel}
\usepackage[utf8]{inputenc}
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{}
\rhead{Share\LaTeX}
\lhead{Guides and tutorials}
\rfoot{Page \thepage}
Pero mi artículo no tiene ninguna reacción.
El siguiente es mi código antes del comienzo del artículo.
\documentclass[12pt]{article}

No sé qué tipo de problema existe. ¿Cómo podemos solucionar este problema?
