Dropdown menu showing gap in between menu and sub menu?


Staff member
I am customizing wordpress twentyeleven theme. Here is the <a href="http://tinkerbin.com/8eZz24PN" rel="nofollow">link</a> for the reference . Here you can see when you hover on menu it will show the dropdown . But you can see there is a gap in between parent menu(company) and sub menu. So how to clear that? Any help and suggestions will be highly appreciable.
