我似乎无法在滚动时创建固定的导航栏。我已经查看了此处发布的一些答案,但是我无法将其用于我的解决方案。我面临的问题是导航栏不会在标题后滚动。它保持在标题下方的固定位置,即使向下滚动也不会移动。有什么想法吗?

//jQuery to collapse the navbar on scroll
$(window).scroll(function() {
if ($(".navbar").offset().top > 50) {
$(".navbar").addClass("top-nav-collapse");
} else {
$(".navbar").removeClass("top-nav-collapse");
}
});

//jQuery for page scrolling feature - requires jQuery Easing plugin
$(function() {
$('a.page-scroll').bind('click', function(event) {
var $anchor = $(this);
$('html, body').stop().animate({
scrollTop: $($anchor.attr('href')).offset().top
}, 1500, 'easeInOutExpo');
event.preventDefault();
});
});
body {
width: 100%;
height: 100%;
}

html {
width: 100%;
height: 100%;
}


@media(min-width:767px) {
.navbar {
position: relative
padding: 20px 0;
-webkit-transition: background .5s ease-in-out,padding .5s ease-in-out;
-moz-transition: background .5s ease-in-out,padding .5s ease-in-out;
transition: background .5s ease-in-out,padding .5s ease-in-out;
background-color: azure

}

.top-nav-collapse {
padding: 0;
}
}
<body id="home" data-spy="scroll" data-target=".navbar-default">

最佳答案

要使导航栏在滚动时保持在同一位置

position: fixed;

在导航的 CSS 中对我有用,但那可能不是你想要的......
