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 includes JSX processing.

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>HTML5 paste image to page</h1>
		<blockquote>Did you know that <code>HTML5</code> lets the user paste an image into the DOM tree? See a demo here and find the code needed in this <a href="https://gist.github.com/STRd6/5286415">Gist</a>. I first came across this code here in a post <a href="http://strd6.com/2011/09/html5-javascript-pasting-image-data-in-chrome/">HTML5 JavaScript Pasting Image Data in Chrome</a>			by <a href="http://strd6.com/author/yahivin/">Daniel X Moore</a> (from 2011!).</blockquote>
		<strong>Instructions</strong>: Copy an image to clipboard (For instance: <strong>Mac</strong>: <code>cmd+shift+ctrl+4</code> and <strong>Win</strong>: <code>Alt+PtrScr</code>), click on the <i>target div</i> to paste the image into, and paste <code>cmd+V</code>		or <code>ctrl+v</code>. <br />
		<strong class="text-info">Version 1.1</strong> Added camera snapshoot sound on paste - use my pen <a href="https://codepen.io/netsi1964/pen/IHwco">Snapshoot sound - snapshoot()
</a> to get that feature on your pens. Also added option to toggle <code>background-size: contain</code> when clicking on pasted image.
