Urgent help: Changing size (depth) of top header

[mcoza]

Hi

 

This is my first ever attempt at editing a theme.

 

I'm using the latest version of Presta with the default bootstrap theme.

 

I would like to be able to put my logo right at the top instead of the long top banner.  However, my logo size is larger in depth than the header area (which seems to be fixed) so my logo gets squashed.

 

I'd like to know how to make the very top header area deeper so my logo fits in. I don't want it to be a fixed size.

 

Also while I'm asking questions, I'd like to adjust the colour of the menu bar (where the signin button is), the cart bar and search bar (all the same colour).  I've tried in global.css but I can't seem to get it to work.

 

I've been battling for 2 days trying to do this myself, so I've finally conceded I need help urgently.

 

Thanks so much!
