Un elemento que podemos añadir a modo de decoracion a nuestro blog estas fechas, es este widget del tiempo que falta para el dia de Navidad. Basado en una idea de Dinamic Drive, lo he rediseñado para darle un toque mas 'cool' con nieve de fondo del contador. Solo teneis que añadir el codigo alli donde querais mostrarlo. En Blogger lo poneis en un gadget HTML/Javascript, y cuando lo querais quitar lo eliminais y ya esta. Si quereis utilizarlo tambien para año nuevo, cambiais el texto y donde pone December 25 lo sustituis por December 31.
