Luc's box

Code to embed this jump in your site:

<div style="position:relative;padding-bottom:56.25%;">
  <iframe style="width:100%;height:100%;position:absolute;left:0px;top:0px;"
  frameborder="0" width="100%" height="100%"
  allowfullscreen allow="autoplay"
  src="https://skydivedesigner.app/j/lucs-box/embed">
  </iframe>
</div>

(This gives a responsive div that keeps its aspect ratio as it expands/contracts)
