i'm trying find out why doesn't work on iphone works great on desktop. tried @ crossbrowsertesting.com , works fine on android phones.. not on iphone.

   // sticky header $(window).scroll(function() {      if ($(window).scrolltop() > 100) {         $('.main_h').addclass('sticky');     } else {         $('.main_h').removeclass('sticky');     } });  // mobile navigation $('.mobile-toggle').click(function() {     if ($('.main_h').hasclass('open-nav')) {         $('.main_h').removeclass('open-nav');     } else {         $('.main_h').addclass('open-nav');     } });  $('.main_h li a').click(function() {     if ($('.main_h').hasclass('open-nav')) {         $('.navigation').removeclass('open-nav');         $('.main_h').removeclass('open-nav');     } });  // navigation scroll lijepo radi materem $('nav a').click(function(event) {     var id = $(this).attr("href");     var offset = 70;     var target = $(id).offset().top - offset;     $('html, body').animate({         scrolltop: target     }, 500);     event.preventdefault(); });

if shown on codepen full html, problem lies within lack of code in html.

create <head> , insert <meta name="viewport" content="width=device-width, initial-scale=1"> it.

read more on setting viewport - google docs.
