Stretch NavBar

[Jibreil]

I need some guidance on how-to stretch the Navbar to fit the length of my message board and I'm very confused as to how to achieve this. Something exactly done on this site.

Thanks in advance :)

it already should be by default

If it isnt, just set a height or width in the navbar template. If you dont know how to, google it.

I did look up on Google, but cannot seem to find anything.

Please can someone help, I just need short instructions to make the navbar stretch to forum width as done on vbulletin.org
