There’s not a quick or easy answer to this but with a bit of creative cajoling we can emulate the same functionality.
What we need is a series of elements we can identify, loop over and then set up so that when we hit their position on the page the previous item is pushed up and the new item becomes fixed. We will need to retrieve the element’s initial position using jQuery’s offset().top method and store it in a data tag so we can reference it later. Then the rest will be calculated as we scroll.
This should do the trick:
var stickyHeaders = (function() {
var $window = $(window),
$stickies;
var load = function(stickies) {
if (typeof stickies === "object" && stickies instanceof jQuery && stickies.length > 0) {
$stickies = stickies.each(function() {
var $thisSticky = $(this).wrap('<div class="followWrap" />');
$thisSticky
.data('originalPosition', $thisSticky.offset().top)
.data('originalHeight', $thisSticky.outerHeight())
.parent()
.height($thisSticky.outerHeight());
});
$window.off("scroll.stickies").on("scroll.stickies", function() {
_whenScrolling();
});
}
};
var _whenScrolling = function() {
$stickies.each(function(i) {
var $thisSticky = $(this),
$stickyPosition = $thisSticky.data('originalPosition');
if ($stickyPosition <= $window.scrollTop()) {
var $nextSticky = $stickies.eq(i + 1),
$nextStickyPosition = $nextSticky.data('originalPosition') - $thisSticky.data('originalHeight');
$thisSticky.addClass("fixed");
if ($nextSticky.length > 0 && $thisSticky.offset().top >= $nextStickyPosition) {
$thisSticky.addClass("absolute").css("top", $nextStickyPosition);
}
} else {
var $prevSticky = $stickies.eq(i - 1);
$thisSticky.removeClass("fixed");
if ($prevSticky.length > 0 && $window.scrollTop() <= $thisSticky.data('originalPosition') - $thisSticky.data('originalHeight')) {
$prevSticky.removeClass("absolute").removeAttr("style");
}
}
});
};
return {
load: load
};
})();
$(function() {
stickyHeaders.load($(".followMeBar"));
});.followMeBar {
background: #999;
padding: 10px 20px;
position: relative;
z-index: 1;
color: #fff;
}
.followMeBar.fixed {
position: fixed;
top: 0;
width: 100%;
box-sizing: border-box;
z-index: 0;
}
.followMeBar.fixed.absolute {
position: absolute;

<br>Here’s the CSS only version:
Before you say “What?! I just went through all of that when there’s a CSS only version?!” It only works in a couple of browsers. Try this in firefox for example:
.sticky {
position: -webkit-sticky;
position: -moz-sticky;
position: -o-sticky;
position: -ms-sticky;
position: sticky;
top: 0;
left: 0;
right: 0;
display: block;
z-index: 1;
background: #999;
color: #fff;
padding: 10px 20px;
}
