Thanks to darkmode-js, a darkmode was added to the framework:

    async function darkmode(Webfan){
        try{
            if(true !== Webfan.c.website.darkmode.enabled && 'true' !== Webfan.c.website.darkmode.enabled){
              return;    
            }
            (new Webfan.Darkmode(Webfan.c.website.darkmode.options)).showWidget();
        }catch(err){
          console.warn(err);    
        }
    }
