La temporada navideña ya es oficial, y al menos los que estan en el hemisferio norte relacionan la nieve con la Navidad
La temporada navideña ya es oficial, y al menos los que estan en el hemisferio norte relacionan la nieve con la Navidad, así que es hora de abrigarnos porque haremos que caiga nieve en el blog.
En esta ocasión usaremos un script de Schillmania que hará que caigan unos finos copos de nieve en el blog y que se irán acumulando al final de la página. Además, la tormenta de nieve se mueve en dirección contraria al cursor, por lo que si movemos el cursor a la derecha entonces la nieve caerá desde la izquierda y viceversa.
Para no complicarnos descargando y subiendo archivos, pegaremos el script directo en un gadget, así podrás quitar la nieve del blog cuando quieras con sólo eliminar el gadget.
