Hi,

1. Change column width in mobile view, now logo has "6" like icon =. It means it's not possible to center.
2. Set column size "10" for logo - for mobile view and "2" for logo column
3. Use this custom CSS for mobile view only

@media (max-width: 580px) {
#sp-logo {margin: 0 auto;}
}

Efekt po

and where to set the point 1,2 . I added the code but it doesn't work

Tip for beginners:

0. You have to use/create a custom header - not predefined. Exactly as it was it previous version of Helix. Predefined header you can disable in "Basic" - "Header" - "Predefined Header" : Off. Then you have full control over grid settings for all views (mobile/tablet/desktop).

But remember that it's still Alpha version (!) So maybe instead of point 0) - right now more advanced custom CSS is needed. For example:

 @media (max-width: 580px) {
 #sp-logo {
    margin: 0 auto;
    width: 80%;
    text-align: center;}
        }

Tested more advanced code and worked without any extra steps.
