here is the URL, thanks for such a fast response!
I spoke too soon 🙂
In homepage .site-header-main appears to work but when you size down to iPad or mobile size it starts giving problems when you open the menu, such as close arrow disappears.
And when you go to other pages, independent of screen size, menu functionality is gone, you can’t click on anything and it gives a lot of problems such as images overlapping on top of it.
What is the correct way of putting this menu position fixed?
ok it’s working now.
