Paso 1
Vamos a Diseño | Edición HTML, expandimos los artilugios y borramos todo para reemplazarlo por los códigos que pegamos más abajo, donde sólo obtendremos una página en blanco a la que Blogger, de modo automático le agrega algunas hojas de estilo, la NavBar (que no se verá) y unos scripts que manejan los widgets aunque no tengamos ninguno. Los post se verán sin ningún tipo de agregado; ni títulos, ni fechas, ni footers ... etc. No habrá nada de nada.
