      initialOpacity: 1, //from 0 to 1, e.g. 0.34 is a valid value. 0 = transparent, 1 = Opaque
      opacitySpeed: 0.1, //values from 0.01 to 1 -> 0.01: slowly appears on screen; 1: appears as soon as the user scrolls 1px
      pageLoader: true //creates a page loader. It is set "false" by default.
    };
