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.

+ add another resource

You're using npm packages, so we've auto-selected Babel for you here, which we require to process imports and make it all work. If you need to use a different JavaScript preprocessor, remove the packages in the npm tab.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

Use npm Packages

We can make npm packages available for you to use in your JavaScript. We use webpack to prepare them and make them available to import. We'll also process your JavaScript with Babel.

⚠️ This feature can only be used by logged in users.

  <h1 id="section1">1. Info</h1>
  <p>I have written the <b>Smooth Anchor Scrolling</b> to improve the weight of your callbacks. I was using Twitter's Bootstrap 3.0 when i wrote this and i'm surprised they haven't yet built anything in. Alas! I have written a super lightweight smooth scroll plugin free for you all to use. I have deliberately <b>not included</b> a plugin such as Scrollspy as i built this for use with Bootstrap that already has Scrollspy within.</p>

  <p><span class="nav"><a class="nav-section4" href="#section4">Go to Section 4</a></span></p>

  <h1 id="section2">S2. Compatibility</h1>
  <p>Currently works well on <b>all modern browsers</b> such as recent versions of <b>Chrome, Safari, Opera, Firefox and IE10+</b>. I have also tested this on current mobile operating systems such as <b>iOS6, iOS7, Jellybean and BlackBerry's OS 10 Software</b>.</p>
  <p>Despite not being tested in previous versions of Internet Explorer i have full-faith that it will work back to <b>IE7</b> and it's predecessor as it's leveraging <b>jQuery</b> functions such as <code>.animate</code>, <code>.closest</code> and others. See the Editor view for full code.

  <h1 id="section3">S3. GitHub</h1>
  <p>The current version of the code is maintained on <b>GitHub</b>, this could be an old version!</p>

🕑 One or more of the npm packages you are using needs to be built. You're the first person to ever need it! We're building it right now and your preview will start updating again when it's ready.
