BANano is a new B4J library to create one-page websites/webapps with (offline) Progressive Web App support. Unlike its big brother ABMaterial, BANano does not rely on any particular framework like Materialize CSS. You will have to write that part yourself, but on the other hand, you have the choice to pick which one.
BANano gives you a set of tools to write your own wrapper around any framework (MiniCSS, Skeleton, Spectre, Bootstrap, …), which then can be easily used to quickly build webapps/websites.
