Ok, it works, except for the fact that the horizontal position of the scrolled sticky menu is changed a bit towards the right edge, if you compare it to the unscrolled menu.
I updated the site so ou can check it.
I think that the minimum option would be that the scrolled menu be in the same horizontal position than that of the unscrolled menu. Even better (but I would like to see how it looks) would be to align the scrolled menu to the center of the header (I don’t know if this could be easily achived or not, what do you think?)
Thank you
