Sticky NavBar onScroll？
我现在正在为自己建立一个网站，我发现这对导航栏位于图像下方的多个网站上的效果非常好，但是当您滚动浏览它时，它会粘在顶部。
例
我怎样才能做到这一点？ 另外，如何使用类似的导航栏样式获得与此网站类似的效果？
这是@Matthew在谈论的内容：

JQUERY
var num = 200; //number of pixels before modifying styles $(window).bind('scroll', function () { if ($(window).scrollTop() > num) { $('.menu').addClass('fixed'); } else { $('.menu').removeClass('fixed'); } }); 希望它有所帮助，我使用了bootstrap navbar。
以下是一些例子
在引导程序中，您可以使用navbar-fixed-top类。
看看以下链接：
固定到顶部： http ： //getbootstrap.com/components/#navbar-fixed-top
修复了Navbar示例： http ： //getbootstrap.com/examples/navbar-fixed-top/
这是一个Bootstrap示例，一旦用户滚过顶部标题，就会将导航栏附加到顶部。
这是另一个使用CSS transition动画附加导航栏的示例
这是一个真实的快速示例，我与jquery和一些非常简单的CSS一起扔。
JS
$(window).on('scroll', function(){ if($(window).scrollTop()>=95 && !$('nav').hasClass('fixed')){ $('nav').addClass('fixed'); } else if($(window).scrollTop()<95 && $('nav').hasClass('fixed')){ $('nav').removeClass('fixed') } });
CSS
.container { height: 1800px; } .header { text-align: center; } nav { background-color: #efefef; border-top: 2px solid #666; border-bottom: 2px solid #666; padding: 15px; width: 100%; } nav ul { margin: 0; padding: 0; list-style: none; } nav li { display: inline-block; } .fixed { position: fixed; top: 0; left: 0; }
HTML
以下是粘性导航栏On-Scroll的示例，其中包含动态高度获取
JS
您需要先添加jQuery Library文件。

$(document).ready(function(){ var num = $(".header-class").offset().top; $(window).bind('scroll', function() { if ($(window).scrollTop() > num) { $('.header-class').addClass('fixed'); } else { $('.header-class').removeClass('fixed'); } }); });
CSS
body { margin: 0px; padding: 0px; } .nav-bar-white { background-color: #125456; width: 100%; } .active-2 { float: right; width: 49%; text-align: right; } .fixed { position: fixed; width: 100%; top: 0; } h3 { color: #fff; } .first { background: #000; width: 49%; display: inline-block; margin: 0px; padding: 0px; border: 1px solid #fff; } .first p { color: #fff; } .second { background: #000; width: 49%; display: inline-block; margin: 0px; padding: 0px; border: 1px solid #fff; } .second p { color: #fff; } ul { list-style-type: none; margin: 0; padding: 0; overflow: hidden; background-color: #300E06; } li { float: left; } li a { display: block; color: white; text-align: center; padding: 14px 16px; text-decoration: none; } li a:hover { background-color: #000; }
