How do I upload/attach an image for you to see?
Cant find a button for it.

Otherwise in this website https://arnfinnjohansen.com/ when you scroll down you will see the logo and the social icons being aligned with the body text on his site.

Looks like the header width is the same width as the “body” content on his site.
I played around a bit on my site http://www.nordicperceptions.com and got pretty close.
changed my container width to 70% and the menu with this code:

#top #header .container {
width: 65%;
max-width: 100%;
}

But its not exact and im not sure if I made it in the correct way.
