How to display HTML content in github README.md?

Question

I am new to github, in README.md want to display a HTML content using an Iframe or something is this possible ?

What I have tried is I just create HTML

Answer 1

Github's markdown interpreter can include HTML. However, there is only so much you can do in HTML. I would suggest checking out this article which provides more information on what tags can be used. Personally, I have never used much more than line-breaks, horizontal rules, etc... Unfortunately, I don't see Iframes mentioned in the article.
