OFF CANVAS TEST PAGE

Trying to have the hamburger icon replaced and be animated on both Desktop and Mobile version of the site using the same Off Canvas menu for all media queries. We use the code from https://docs.generatepress.com/article/animated-hamburgers.

All the modifications and additional code are marked with “modified/added by Tom”.

NOTES:

The Mobile Breakpoint is set to 2000.

Mobile Header is off, Navigation as Header is on.

Creates Javascript error, will be fixed in GeneratePress 3.1.

PHP (three snippets)
