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.

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.

              <h3>Loading videos based on screen sizes</h3>
<p>Chrome doesn't support inline media queries for the source in a <code>video</code> tag like the <code>picture</code> element. Sometimes you want to load a different video based on the screen size, such as a different aspect ratio. This is a simple script to accomplish this. It could easily be extended to a resize event. </p>

	<video id="bgvid" preload="auto" autoplay="" loop="" muted="" playsinline="" class="" data-desktop-vid="" 
<h3>Inverse to demo multiple vids</h3>
