Logo in top-header section

Hi Everybody!

I'm trying the following things on Divi:
First nav bar: logo centered + some icons on the right (let's call it ... hum top-header section)
Second nav bar: main menu center. (= main-header section)
= logo aligned with the icons from the top-header section.

But what i success to do is having the top-header with icons on the right, then the main-header section with logo centered first, then the menu displayed below it. :-(

I've look at some posts here and on elegantthemes (https://www.elegantthemes.com/blog/...custom-global-header-with-divis-theme-builder) but ... there is no scrolling option with this tutorial and i would like to change size and some css when scrolling.

My trouble looks, for me, just to find a way to put the logo, not in the main-header section but in the top-header section but if you have better solution or idea... it's more than welcome!!

Thanks in advance!

 

Oh, sorry for the bad explanation.
