Help needed to hide the header of Krystal in mobile only

[arunnbabu81]

I am using a hack given by Nicolas Petton in TW google group to enable his NoteBook theme only in mobile (not in desktops). But the header of Krystal is persisting and partly hiding the sidebar when I open the sidebar in mobile (with notebook theme active). Is there any way to hide the header only in mobiles ? I am attaching a demo wiki with relevant tiddlers set as default home page tiddlers.
