A common web trend is to allow a static header stick to the top of the page when scrolling the page. I imagined there would be quite a bit to it but it turns out it’s very easy to accomplish.
First create a css class, this will set the element to be fixed in place.
.navbar-fixed {
top: 0;
z-index: 100;
position: fixed;
width: 100%;
}
Next add the following jQuery code:
var navpos = $('#header').offset();
$(window).bind('scroll', function() {
if ($(window).scrollTop() > navpos.top) {
$('#header').addClass('navbar-fixed');
} else {
$('#header').removeClass('navbar-fixed');
}
});
This works by created a navpos var that holds the heigh of the element, then using bind on scroll to run a function that determined if the scroll is higher then the height of the element. When that is true give the element a class of navbar-fixed otherwise remove the class.
To see this in action scroll on this blog to see the header move with the page. (Only when running on a normal desktop view so no mobile support.)
