Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

<h2>What's it all about?</h2>

<p>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.</p>

<h3>Why use it?</h3>

<p>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&hellip; </p>

<p>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.</p>

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

<h3>How does it work?</h3>

<p>At it's most basic headroom.js simply adds and removes CSS classes from an element in response to a scroll event:</p>

<pre class="language-markup"><code>&lt;!-- initially --&gt;
&lt;header class="headroom"&gt;

&lt;!-- scrolling down --&gt;
&lt;header class="headroom headroom--unpinned"&gt;

&lt;!-- scrolling up --&gt;
&lt;header class="headroom headroom--pinned"&gt;

<p>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.</p>


<p>Using headroom.js is really simple. It has a pure JS API, and an optional jQuery/Zepto-compatible plugin.</p>

<h3>With pure JS</h3>

<pre class="language-javascript"><code>// grab an element
var myElement = document.querySelector("header");
// construct an instance of Headroom, passing the element
var headroom  = new Headroom(myElement);
// initialise
    <a class="btt btn btn--plain hide-from-print" href="#" id="btt">Top <i class="icon icon--up"></i></a>

<script src=""></script>





                (function() {
    var header = new Headroom(document.querySelector("#header"), {
        tolerance: 5,
        offset : 205,
        classes: {
          initial: "animated",
          pinned: "swingInX",
          unpinned: "swingOutX"
