Full width/height logo

Hello Amazing HB team!

I’m have a great time with your theme and with your support.

I’d like to have a full-width/height header but I think I can work-around this is I could upload a logo of the correct size.

On mobile, the size of the logo from your simple blog: http://hb-themes.com/themes/highend/simple-blog/ looks great on the mobile, but is too small for the desktop version I’m trying to make.

On my old site, the logo fills from the topbar to the navigation menu, and is full width 1140 (See screenshot)

On the new HB site, It looks like this: http://www.alekhess.com/

Any help is greatly appreciated!
