Blank Screen on Android and Browsers

In order to view and study offline and locally framework7-2.1.2 I create a “build” directory inside “kitchen-sink” with “css\framework7.css” and “js\framework7.js” subdirs and files respectively. Also in Xampp apache server I define a vitual host for this “kitchen-sink”, along with a site name in the hosts local DNS file in windows.

All works fine with chrome, http:// web access via the site name, but with file://…/index.html a blank screen appears.

The same blank screen appears in Firefox and in Edge browsers, using both access, via http:// and via file://

Clear caching and others changes in browsers did not resolve the problem, a blank screen appears.

In all browsers the Page Source is the index.html as well.

I am using Firefox Version 59.0.1 64-bit, Chrome Version 63.0.3239.84 (Official Build) (64-bit), Microsoft Edge 38.14393.1066.0, Microsoft EdgeHTML 14.14393

What could be happen?.

Why in chrome the file:// does not work and the http:// works ok?.

Thanks in advance,
