[byzard]

Estimados,
alguien mas experto en el tema del css me puede ayudar.

foto2


como se observa, no se porque en el explorer me lo muestra bien(ver foto1), pero en el firefox se ve mal(ver foto2). Ya me paso otra cosa, que en el menu del siderbar no me mostraba el fondo en firefox, lo solucione comentando la linea del /*float: right;*/ en el siderbar. pero esto que me a sucedido ahora, no tengo idea en que parte del codigo del style.css podria estar.

dejo el css

Código:
