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>The spinning hexagonal click-spot show</h1>

<p>A furtherance to a click animation I saw a while back over on codrops.<br>Rewritten to remove library dependencies, added spin, et voila&hellip;</p>

<div class=grd_parent>
  <div class=grd-2>

    <article class=grd_itm>
      <a class=grd_lnk-small data-spot href="#">
        <div class=grd_copy>Click me (link)</div>

    <article class=grd_itm>
      <button class=grd_btn-small data-spot>
        <div class=grd_copy>Click me (button)</div>

    <article class=grd_itm>
      <a class=grd_lnk data-spot href="#">
        <div class=grd_copy>Click me (link)</div>

    <article class=grd_itm>
