Hi,
We have all tried this now and none of us can make this one work. Here is the code I tried, I was careful not to insert a CR after the tag close.
ASE says we need to just inline the iframe without any carriage returns after it and it should work, as their example had only a width and no height I have taken the height attribute out of the code as well <iframe src=”https://cdn.knightlab.com/libs/timeline3/latest/embed/index.html?source=1xuY4upIooEeszZ_lCmeNx24eSFWe0rHe9ZdqH2xqVNk&font=Default&lang=en&initial_zoom=2& width=”100%” frameborder=”0″></iframe> now we are after the iframe with no CR before it.
This code is rendered here https://igor.gold.ac.uk/~mas01af/datablog/test-posts/
Thanks,
Andy
