   prevencion.cc — hoja de estilo unica

   Una sola hoja para las seis paginas: una peticion, sin librerias y sin nada
   que se pueda caer desde fuera. La web anterior era de 2012, no tenia
   viewport y se veia minuscula en el movil; esta se hizo pensando primero en
   el telefono, que es de donde llega la mayoria de las visitas.
