Is it possible for me to have different header settings for different pages? On my portfolio pages, I want the sticky header to shrink in size, but I don't want that to happen for the rest of my pages. Is this possible? Also, how would I make sure the logo shrinks as well, rather than just disappearing?

This is not my site, but I want something like this: http://www.getaha.com/project/tbg-partners/

Or this: http://focuslabllc.com/work/haywire

Thanks!
