Fixed (sticky) toolbars with jQuery

Here’s a little snippet of code that let’s you create sticky toolbars like they use in Magento for example :)

Include this in your js somewhere and then just call $(‘.toolbar’).fixed();

$.fn.fixed = function() {
return this.each(function() {
var header = $(this);
var offset = header.offset();
var floater = $('').append(header.clone(true));
floater.hide().appendTo(document.body).addClass('floating-toolbar');

$(window).scroll(function() {
var s = $(this).scrollTop();

if (s > offset.top) {
header.css('visibility', 'hidden');
floater.show();
} else {
floater.hide();
header.css('visibility', 'visible');
}
});
});
};

And here’s some css to make it work.
.floating-toolbar {
position: fixed;
top: 0;
left: 0;
width: 100%;
opacity: 0.85;
}
