</div>
CSS
body {
margin:0;
padding:0;
font-family: Arial, sans-serif;
}
header {
position: relative;
width: 100%;
height: 80px;
line-height: 80px;
background: #CCCCCC;
color: #333333;
padding-left: 25px;
}
header.fixed {
position:fixed;
top:-80px;
left: 0;
right: 0;
z-index:8888;
transition:0.3s top cubic-bezier(.3,.73,.3,.74);
}
body.on-scroll header.fixed {
top:0;
}
.content {
padding: 25px;
background: #fff;
line-height: 1.4;
color: #333;
min-height: 2700px; /* You can remove this,is just for demo purpose */
}
jquery:
(function($){
$(document).ready(function() {
var $header = $(".header"),
$clone = $header.before($header.clone().addClass("fixed"));
$(window).on("scroll", function() {
var fromTop = $(window).scrollTop();
$("body").toggleClass("on-scroll", (fromTop > 200));
});
});
})(jQuery);
Here's a jsfiddle example.
