This page demonstrates Facet with ScrollUp over a full page header image.
Facet is using an Overlay menu with the Genie effect.
This demonstrates perfectly how a modern full page navigation can be a universal solution for all screen sizes.
Facet does not have to use a hamburger.
You can use custom open and close images as shown on the Genie and Curtain overlay example pages.
Alternatively the Facet Launcher stack allows for a fully customised launch solution any where on your page - even in other menu systems.
