Hi @mimfox, I checked in Google Chrome latest version and it seems to be working for me, did you get it restyled ok?
To use the smooth scroll section linking, there are a few conditions to setup to get that to work best. Take a peek here: Getting Webflow's smooth scroll script to align correctly with fixed headers/navigation
I would recommend a couple of things.
On the navbar 4, drop that inside of a Section and then give the Section a fixed position instead of the navbar
Set the navbar 4 in elements settings to “disable scroll offset when fixed”:
Nest the Navbar 3 inside of another section, and set it’s tag to header:
I would also remove any margins on sections under the body and only use padding.
I hope this helps.
