This evening I started a side project to all of my other ones that use Bootstrap and the Bootstrap4XPages plugin. I thought it would be useful for me to have a simple starting point that comes with all settings, CSS, Java and stuff to start just right from the scratch with a new application. There are only a few tweaks needed to create an application with a complete layout, dynamic navigation items (bean-based) and with all other resources you may want to use.
The sources can be found on GitHub here and a live demo (as always) can be seen here.
I also started some other templates with Foundation and UIKit. You can also find them on GitHub:
