I made a fist “Home page” (see attachements - 01 ) and then based on that I made a duplicate (copy - see attachement - 02) and build a “Service Page”. Everything went well, except the navigation menu in the mobile devices. The info (divs and classes, are all there, but the display is not correct!). The navigation is a custom navigation (meaning that I followed the instructions given here: https://webflow.com/blog/how-to-customize-your-hamburger-menu-in-webflow).
Thank you for your support.
