How to add Oembed jsfiddle to habr?

Question

JavaScript

I can't add Oembed to an article. In preview mode and nothing works
Information from oembed.com did not help. How to add any Jsfiddle to a post.
I have been changing screenshots of maps and other information in the publication every day for two weeks now. Frames don't work either. Styles probably too. Attempts to use markdown also did not give anything. Markdown styles don't work either. Markdown selectors(Class ID) don't work either.

I need to generate a simple timeline, css code is enough. However, even css could not be inserted.

Many thanks to Boomburum for the help.
The correct combination is this: I tried to load only the result: Because there is most likely a regular expression checking the validity. Options such as<oembed>https://jsfiddle.net/feq524ya/</oembed>

<oembed>https://jsfiddle.net/feq524ya/embedded/result/</oembed>

do not work. I need to show the result immediately. And Oembed displays the code in front. Thus the situation was abandoned unresolved.
