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.

Add External Scripts/Pens

              <h1>Laying Out Calendar Events</h1>
<p>This is a quick grid demo for laying out events for a calendar week. Requires <code>display:contents</code> so this'll only work in Chrome (if you have experimental features turned on) and Firefox. See <a href="https://caniuse.com/#feat=css-display-contents">Can I Use</a> for more.</p>
<p>Check out the <a href="https://www.youtube.com/watch?v=GD1IKgrWTgU&feature=youtu.be">accompanying YouTube video</a></p>
