                Using "visibility:hidden" over "display" none because:

                1)      As the "position" property for submenus is set to "absolute", they are out of
                        the document flow and take up no space.  Therefore, from that perspective use of
                        "display:none" is redundant.

                2)      According to MSDN use of "display:none" is more expensive:
                        "Display is the more expensive of the two CSS properties, so if you are
                        making elements appear and disappear often, visibility will be faster."
