Hi Rue,
Yes, I think we’ve already talked about this issue before and you’ve told us that you’ve decided not to make the header stick on mobile sites, even though my coder confirmed to me that this is a normal thing for most sites. I’ll ask my coder again about what specifically she might have done before. We’ll try out the solution you’ve provided but to be sure that I didn’t misunderstand you, does the fix you’ve provided make sure that the header stays at the same size? Or that the content is never hidden behind it? Which is the problem as the site makes a jump when you start scrolling because the content only starts being displayed behind it then.
Cheers,
Andreas
