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.

	<h1>Infinite Scroll + Pagination Experiment</h1>
	<p>After a poll by <a href="https://twitter.com/smashingmag">@smashingmag</a>, <a href="https://twitter.com/TimSeverien/status/693186708494536704">I got the idea to combine pagination and infinite scroll.</a> The former gives the user control, but needs more effort. The latter lacks control, but requires no special interaction.</p>
