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.

JavaScript

Babel is required to process package imports. If you need a different preprocessor remove all packages first.

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.

                <article>
  <section id="part-one">
    <h1>CodePen Challenge</h1>
    <p>Hover over the title above. You’ll see a link appear. We want you to style that link! The markup for each title and link, just so you know, looks like this: 
    <pre>
    &lt;h1&gt;
      &lt;span&gt;Codepen Challenge&lt;/span&gt;
      &lt;a href="#part-one"&gt;#part-one&lt;/a&gt;
    &lt;/h1&gt;</pre></p>
  <p>Make sure you retain the <a href="https://codepen.io/tag/tutplus/">tutsplus</a> tag on your pen so we can identify it–good luck!</p>
