<h1>Smoothly change flex direction with GSAP's Flip plugin</h1>

<button id="changeLayout" class="button">change</button>
<div class="group">
  <div class="box">Common "FLIP" techniques employed by other tools won't work with flex elements because of the way browsers handle width/height. 
  <div class="box">Simply set <code>absolute: true</code> to have GSAP's Flip plugin make the elements position: absolute during the flip to work around challenges with flex and grid layouts. 
  <div class="box">When the flip animation is done, elements get reverted back to their normal positioning and everything appears seamless.</div>
  <div class="box">Happy flipping!</div>
