Menú horizontal con submenúes y un efecto de balanceo.

Este es un menú horizontal con submenúes y un efecto de balanceo para nuestro blog de Blogger. Fácil de colocar, tan solo un código entero y podemos ponerlo en un gadget HTML/Javascript o donde mejor quede en nuestro blog. Abrimos un gadget HTML/Javascript y dentro de el pegamos este código entero:

<div id="containerbalanceo">
