Thanks drake.
Works like magic and solved another problem while adding it

.
The url is
http://rng.org.au/ (obviously the rest of the content is just a placeholder).
I used #nav.continuous to get rid of white spaces between the individual buttons.Note that the left indent was created with a left inset border.
Three questions:
1. How can I increase the size of the buttons so that the 'outcomes' and 'media' buttons will cover the orange area on the right?
2. Similarly, getting sufficient width of button to fit a the long name in the 'People' menu?
3. Finally

, how to stretch the background image to fit the whole length of the wrapper?
Thanks a lot!
