+        * 976px - which is the maximum width where the aside is shown in
+        * mobile style - because on chrome-based browsers (desktop and
+        * android) the sticky plugin in mobile style causes the browser to
+        * scroll back to top the main content, making it impossible
+        * to navigate.
+        * A side effect is that the sitky aside isn't really responsive,
+        * since is enabled or not at page loading time.
