Give your pages some headroom. Hide your header until you need it.

What's it all about?

Headroom.js is a lightweight, high-performance JS widget (with no dependencies!) that allows you to react to the user's scroll. The header on this site is a living example, it slides out of view when scrolling down and slides back in when scrolling up.

Why use it?

Fixed headers are a popular approach for keeping the primary navigation in close proximity to the user. This can reduce the effort required for a user to quickly navigate a site, but they are not without problems…

Large screens are usually landscape-oriented, meaning less vertical than horizontal space. A fixed header can therefore occupy a significant portion of the content area. Small screens are typically used in a portrait orientation. Whilst this results in more vertical space, because of the overall height of the screen a meaningfully-sized header can still be quite imposing.

Headroom.js allows you to bring elements into view when appropriate, and give focus to your content the rest of the time.

How does it work?

At it's most basic headroom.js simply adds and removes CSS classes from an element in response to a scroll event. This means you must supply your own CSS styles separately. The classes that are used in headroom.js that are added and removed are:

<!-- initially -->
<header class="headroom">

<!-- scrolling down -->
<header class="headroom headroom--unpinned">

<!-- scrolling up -->
<header class="headroom headroom--pinned">

Relying on CSS classes affords headroom.js incredible flexibility. The choice of what to do when scrolling up or down is now entirely yours - anything you can do with CSS you can do in response to the user's scroll.


Using headroom.js is really simple. It has a pure JS API, plus an optional jQuery/Zepto plugin and AngularJS directive.

Install with npm

npm install headroom.js --save

Install with bower

bower install https://unpkg.com/headroom.js/bower.zip --save

Using Headroom.js with a CDN

A universal build (suitable for script tags, CommonJS, and AMD) is available from unpkg.com:


With pure JS

Include the headroom.js script in your page, and then:

// grab an element
var myElement = document.querySelector("header");
// construct an instance of Headroom, passing the element
var headroom  = new Headroom(myElement);
// initialise

With jQuery/Zepto

Include the headroom.js and jQuery.headroom.js scripts in your page, and then:

// simple as this!
// NOTE: init() is implicitly called with the plugin

The plugin also offers a data-* API if you prefer a declarative approach.

<!-- selects $("[data-headroom]") -->
<header data-headroom>

Note: Zepto's additional data module is required for compatibility.

With AngularJS

Include the headroom.js and angular.headroom.js scripts in your page, and include the Headroom module

angular.module('app', [
// your requires

And then use the directive in your markup:

<header headroom></header>
<!-- or -->
<!-- or with options -->
<headroom tolerance='0' offset='0' scroller=".my-scroller" classes="{pinned:'headroom--pinned',unpinned:'headroom--unpinned',initial:'headroom'}"></headroom>

Note: in AngularJS, you cannot pass a DOM element as a directive attribute. Instead, you have to provide a selector that can be passed to angular.element. If you use default AngularJS jQLite selector engine, here are the compliant selectors.


Headroom.js can also accept an options object to alter the way it behaves. You can see the default options by inspecting Headroom.options. The structure of an options object is as follows:

    // vertical offset in px before element is first unpinned
    offset : 0,
    // scroll tolerance in px before state changes
    tolerance : 0,
    // or scroll tolerance per direction
    tolerance : {
        down : 0,
        up : 0
    // element which is source of scroll events. Defaults to window
    scroller : element,
    // css classes to apply
    classes : {
        // when element is initialised
        initial : "headroom",
        // when scrolling up
        pinned : "headroom--pinned",
        // when scrolling down
        unpinned : "headroom--unpinned",
        // when above offset
        top : "headroom--top",
        // when below offset
        notTop : "headroom--not-top",
        // when at bottom of scoll area
        bottom : "headroom--bottom",
        // when not at bottom of scroll area
        notBottom : "headroom--not-bottom"
    // callback when pinned, `this` is headroom object
    onPin : function() {},
    // callback when unpinned, `this` is headroom object
    onUnpin : function() {},
    // callback when above offset, `this` is headroom object
    onTop : function() {},
    // callback when below offset, `this` is headroom object
    onNotTop : function() {}
    // callback at bottom of page, `this` is headroom object
    onBottom : function() {},
    // callback when moving away from bottom of page, `this` is headroom object
    onNotBottom : function() {}


Head over to the headroom.js playroom if you want see some example usages. There you can tweak all of headroom's options and apply different CSS effects in an interactive demo.

Browser support

Headroom.js is dependent on the following browser APIs:

All of these APIs are capable of being polyfilled, so headroom.js can work with less-capable browsers if desired. Check the linked resources above to determine if you must polyfill to achieve your desired level of browser support.

Contributions & Issues

Contributions are welcome. Please clearly explain the purpose of the PR and follow the current style.

Issues can be resolved quickest if they are descriptive and include both a reduced test case and a set of steps to reproduce.
