Hover - grey line -- around nav buttons - even with a zero border


I am trying to put some css navigation buttons (no graphics) on "top"of an existing graphic.

Even though I don't have CSS borders in the "buttons" I am seeing little gray "ghost lines" on at least the top and bottoms of the buttons -- which is preventing me from getting the buttons to blend in with the background graphic color of the navigation area.

You can see what I am talking about on this development site:


NOTE:  I am *assuming* that the light gray "borders" visible on the navigation are not caused by CSS -- I don't see any clues via firebug.  I didn't create most of the css so maybe there's some border css hiding somewhere -- perhaps cascading from another css setting.

ANYWAY I am talking about the blue navigation on top banner area of the page that starts with "home   about us" etc.


Right now the bottom of the css nav you can see the slight gray line on the bottom.  Perhaps it is caused by some browser default - I see it in both firefox and IE.

Set on the CSS here:
<div class="yuimenubar yuimenubarnav yui-module yui-overlay visible" id="ariyuimenu_ariyui87" style="z-index: 0; position: static; display: block; visibility: visible;">
the borders are caused by the definition ".yui-skin-sam#ariyui87 .yuimenubar" in css_loader.php
