dark / light mode

[admin]

Add this to Custom JavaScript:

Code:

$(function(){
  if (window.Storage) {
    var dark = !!Storage.get('darkmode', '');

    $('body').toggleClass('dark', dark);
    
    $('.toggle-dark-mode').off('vclick').on('vclick', function() {
      dark = !dark;
      Storage.set('darkmode', dark ? 'y' : '');
      
      $('body').toggleClass('dark', dark);
    });
  }
});

Create a dummy object and attach a visualization element to it. Set Additional classes to toggle-dark-mode
Clicking this element will toggle between light/dark mode. This setting is stored in browser's local storage.
