固定的位置不适用于粘性菜单

Question

I added this class ".sticky" by javascript to the nav but sticky menu not working correctly.

.sticky {
position: fixed;
width: 100%;
left: 0;
top: 0;
z-index: 100;
border-top: 0;
-webkit-transform: none;
transform: none;
}

javascript code

//sticky menu
 var stickyNavTop = $('.main-navbar').offset().top;
 var stickyNav = function(){
    var scrollTop = $(window).scrollTop();

    if (scrollTop > stickyNavTop) { 
        $('.main-navbar').addClass('sticky');
    } else {
        $('.main-navbar').removeClass('sticky'); 
    }
};
stickyNav();
$(window).scroll(function() {
  stickyNav();
});

Answer 1

Add this css:

.scotch-panel-canvas {
    transform: none !important;
    -ms-transform: none !important;
    -moz-transform: none !important;
    -webkit-transform: none !important;
 }

Answer 2

Please remove inline styles from the scotch-panel-canvas div then it works fine...

remove this style: style="position: relative; height: 100%; width: 100%; transform: translate3d(0px, 0px, 0px); backface-visibility: hidden; transition: all 300ms ease;"

i don't how this inline css coming from but you should remove this. I think this style coming from some jquery. When u remove this code it works fine...

and also increase the z-index value

Answer 3

Using position: fixed; and top: 0px; should be enough.
