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.

		<p>If we reparent the black &lt;div&gt; into a new rotated &amp; scaled container (altering the DOM structure), how could we animate there seamlessly? Use the "FLIP" animation technique! Press the right arrow to begin.</p>

		<p><strong>"First":</strong> Get the initial state.<br><code>const state = <a href="https://greensock.com/docs/v3/Plugins/Flip/static.getState()">Flip.getState(targets)</a></code></p>
		<p><strong>"Last":</strong> Put elements in their final state. In this case we'll place the element in the new container &lt;div&gt; which results in a totally different position, scale, and rotation.</p>
		<p><strong>"Invert":</strong> Make the element <i>appear</i> in its previous position/size by applying offsets instantly. That way, it <i>looks</i> like it hasn't moved yet. <i>Note: we animate this step in the demo to illustrate what normally happens immediately.</i></p>
		<p><strong>"Play":</strong> Animate the removal of those offsets.<br>
			<code><a href="https://greensock.com/docs/v3/Plugins/Flip/static.from()">Flip.from(state, options)</a></code> returns a GSAP timeline so you can add other animations, control it, etc.
		</p>

		<p>GSAP's <a href="https://greensock.com/docs/v3/Plugins/Flip">Flip Plugin</a> makes this a breeze! </p>
