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.

  <p>A responsive navigation menu for a project of mine. I needed the top level links (team, news, our services, our work, contact us) to be still clickable (because they send the user to a special page) so I needed to "split" the "presentation" link with an arrow for the responsive part.</p>
  <p> Also note that font for the arrow are loaded from my dropbox so it won't appear on Firefox and IE (crossdomain issues I guess)</p>
