Reading local HTML content with a browser

You can not browse local HTML (...) content with the browser. This is a side-effect of confining the browser with apparmor to prevent disclosing sensitive information from the files in the phone.
But there is a workaround which I do use to read my diary, written in HTML and niced with photos. Create a MyWebContainer.desktop file with the following lines:
[Desktop Entry]
Exec=webapp-container --enable-addressbar --enable-back-forward --webappUrlPatterns=/home/phablet/diario2016/* /home/phablet/diario2016/diario.html
and place this as root into the place: ~/.local/share/applications/MyWebContainer.desktop
Ofcourse, you need as well some nice icon file. After this, reload the app screen and it should show up.
I write it on my netbook and just copy it over with
$ rsync -arv diario2016 [email protected]:.
