Header Logo and Navigation Bar Questions

Hi there,

I originally mistakenly asked these questions at the end of another thread which I see is still marked as resolved, so I guess I should start a new topic.

I’ve referred to the solution you offered here for making the logo full width: https://archived.seventhqueen.com/forums/topic/logo-cannot-go-full-width

I have some supplementary questions related to the same topic. I’ve just bought and installed Kleo theme here: http://administrexdemo.expoco.com.au/

I’m trying to recreate the layout in the attached screengrab, so I’m hoping you can answer the following:

1. Is it possible to have the Navigation Bar sticky, and let the rest of the Header section scroll up normally? I want the nav to start below the Header/Logo as shown, and then stick to the top when the page scrolls up.
2. Is is possible to have a different Header and Nav on the BuddyPress/BBPress pages? I’d like a very simple Nav on these pages, so it doesn’t clash with the user’s cover picture.
3. Is it possible to add a 1 pixel white border around the Navigation Bar, and the Menu items, similar to the screengrab?
4. Finally, there is a 1px white gap on the left of the Logo, even though I have the full width code you’ve provided above – do you have a fix for this?

Thank you in advance for your help!
