Eliminate Blanks

Hi Sakin, I use this page http://codex.wordpress.org/Creating_Horizontal_Menus in order to create a menu. The result is this http://www.focusblog.site40.net/ But the problem is that there are blanks between the padding style as you can see and i want to eliminate this blank. I also want to put borders but i can't find how. It would be very helpful if you could show me css code to add. Thank you.
