Question

code review

1 Help how to remove the vertical scroll?
2 I couldn't use this code for my project(

var $navFix = $(".meny"); 
 			$(window).scroll(function(){
          if ( $(this).scrollTop() > 120){ // 120 это высота прокрутки
     			 $navFix.addClass("fixed");
    			} else if($(this).scrollTop() <= 120) {
    			 $navFix.removeClass("fixed");
    }
  });

Here is my project.

There is nothing to evaluate there, since there is nothing stupidly there.
As for the menu, it's not at all clear why JS was needed there.
If the menu is ALWAYS fixed at the top?
The usual one position: fixed;is enough without any JS.
This is a comment on a previous question.
"Gags" when scrolling through sections just kill.
