Add css and instruction for responsive iframe embed
I think we are going to follow this:
https://css-tricks.com/responsive-iframes/
Will have to request editor to add the following html around iframe contnet:
<div style="--aspect-ratio: 16/9; /* width: 100% */">
</div>
Without width, the div mysteriously doesn’t work, may need to take a look at our theme css.
The --aspect-ratio
custom property will be added to our theme css.
