Menu bottom border line !


I recently changed the menu color on my site to white, i wanted to add a black bottom border line to the menu.

Could you please advise how to implement this.

Also I have a header slider on my home page and as you know the menu is see through in sydney and integrates with he header slider. How can i separate the two. How can i move the header slider to be under the menu not behind it?

Your help is much appreciated


Please post a link to your website, so I can check.

Kind Regards,
