I found such a problem on the site, and it is present only on the iPhone. If you try to scroll the page down with your finger, dragging your finger and releasing it from the screen onto the andriod page will scroll downward for a while. On the iPhone, everything stops right away. Moreover, in order to scroll, you need to press the finger directly with effort. Who prompts what, may have encountered similar? The site can be viewed here: http://myiconskin.sopteh.beget.tech/
UPD: The scroll event is:
$(document).ready(function(){ var $menu = $('#logo'); var $menufix = $('#logo_fix'); $('body').scroll(function(){ if ( $(this).scrollTop() > 1 && $menu.hasClass('normal') && $menufix.hasClass('hide') ){ $menu.removeClass('normal').addClass('hide'); $menufix.removeClass('hide').addClass('normal'); } else if($(this).scrollTop() <= 1 && $menu.hasClass('hide') && $menufix.hasClass('normal')) { $menu.removeClass('hide').addClass('normal'); $menufix.removeClass('normal').addClass('hide'); } }); });
