Todos los que utilizamos la plataforma de Blogger, conocemos el gadget de entradas populares, que nos informa de los articulos mas visitados de nuestro blog. El aspecto 'de casa' de este artilugio es un poquito simple, pero siempre se puede rediseñar como ya os he mostrado en otras tantas entradas. En este caso lo vamos a 'convertir' en un cubo que ira girando con efecto 3D, mostrando los posts en cada una de sus caras.Para instalarlo en el blog, obviamente debemos tener el gadget de entradas populares, marcando solamente la casilla de imagen en miniatura, como podeis ver en esta imagen.
Despues, deberemos copiar el siguiente codigo y pegarlo en un gadget HTML/Javascript y situarlo encima del anterior, como podeis observar en la imagen de la izquierda. Guardamos los cambios y la disposicion y ya lo tenemos. Facilito ¿Verdad? Si lo deseais, podeis ver una demo haciendo click aqui.<style type="text/css">
