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.


Headroom.js is available on npm. To install:

npm install headroom.js --save

# or...
yarn add headroom.js

A a universal build (suitable for script tags, CommonJS, and AMD) is available from


For complete documentation please visit the headroom.js website.

Quick start

After installing headroom.js. The following JS will create and initialise a headroom instance:

import Headroom from "headroom.js";

// select your header or whatever element you wish
const header = document.querySelector("header");

const headroom = new Headroom(header);

Then you can add the following CSS to your page:

.headroom {
  will-change: transform;
  transition: transform 200ms linear;
.headroom--pinned {
  transform: translateY(0%);
.headroom--unpinned {
  transform: translateY(-100%);

You should now see your header slide in and out in response to the user's scroll.
