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.

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.

              <h2>Dividers (horizontal rule) <code>&lt;hr&gt;</code></h2>

<p>Use dividers to define thematic breaks between paragraphs. To denote the end of one section of a page and the start of another, it's better to use the <code>&lt;section&gt;</code> tag. <code>&lt;hr&gt;</code>'s have top and bottom margin to provide spacing between sections of content.</p>
