Cool stuff! Thx Danilo.

I tested it also on a smartphone. Unfortunately there is a problem with the Safari browser when using the landscape mode and going to full screen. Then you can only click the button, but not the AppMenu.

I see. Looks like mobile Safari does not like clicks at the very top of the screen.

It actually works if you don't touch the screen at the very top.
If you hit the menu buttons at the bottom, it works. :D

You can make it work better for mobile landscape mode by adding a margin to the top of the screen.
I tested with 10 pixels and it worked, 15 pixels was perfect.

I added the top-margin in the AddMenuButton() procedure at line 53:

Old line:
Code: Select all
    ! btn.style.margin     = '0';       btn.style.padding    = '10px 10px';

New line:
Code: Select all
    ! btn.style.margin     = '15px 0 0 0';       btn.style.padding    = '10px 10px';


If you would like to make the menu buttons larger, you could increase the font size at line 51,
or increase btn.style.padding at line 53.

Here is a screenshot with added top-margin on iPhone:

Yeah, thx. That seems to mitigate the problem. However, with a margin at 15px, you still have to tap very close to the bottom of the appbar, to get an reaction.
May we have to use some meta tags in the header, to make the page behave more like an app.

In the chat you had shown new fancy gui elements. Especially the ToggleCheckbox would interest me.
Do you plan to post the tip on how to restyle it?
