I have set naviagation logo to static and sticky. In static position all is fine but in sticky position I see a narrow offset in the left side of webpage in desktop view.

There were two problems. Surprisingly changing full widht to contained solved extra margin in header and primary navigation but there is also wp show post pro plugin causing extra margin in posts and pages. the latter one is still unresolved because it is related to wp show post pro plugin and not theme.
