Adding iFrame to Obsidian Note

I need to add embeds to my Obsidian notes a specific way so that they render on my website (chaseadams.io) and so that they render properly in my notes.

When adding an embed, the iFrame needs to be added with a div with class="iframe-wrapper".

As an example, a Loom would look like this:

<div class="iframe-wrapper">
	<iframe 
	src="https://www.loom.com/embed/5ccaf045fe15410fb9369a70c3dc7210" 
	webkitAllowfullScreen mozAllowFullScreen allowFullSscreen>
	</iframe>
</div>

It would render like this in Obsidian:

and like this in my website:

The CSS that makes this work:

.iframe-wrapper {
  position: relative;
  width: 100%;
  padding-bottom: 56.25%;
  margin: 2rem 0;
  height: 0;
}

.iframe-wrapper iframe {
  border: none;
  width: 100%;
  height: 100%;
  position: absolute;
  top: 0;
  left: 0;
}

This allows the .iframe-wrapper to control the display of the iframe.
