Dear bassel

Let us have a look at the different parts. A rootmenu with two menu items contains the following elements.

What does all these abbreviations mean?

RtMnItLeSeNo: Rootmenuitemleftseparatornormal
RtMnItRiSeNo: Rootmenuitemrightseparatornormal
RtMnItMiSprt: Rootmenuitemmiddleseparator
LeftHTML: Left html
RtMnItBrArrw: Rootmenuitembreadcrumbarrow
RightHTML: Right html
ArrwDown: Arrow down

The MainMenu_MenuBreak .css style is only the part between two menuitems that I've give the name Rootmenitemmiddleseparator.

  Hope this will help.
