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
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.
You can use svg to work around, example code (./path/example.svg):
<svg width="100" height="100" xmlns="http://www.w3.org/2000/svg">
<foreignObject width="100" height="100">
<div xmlns="http://www.w3.org/1999/xhtml">
<ul>
<li>text</li>
</ul>
<!-- Other embed HTML element/text into SVG -->
</div>
</foreignObject>
</svg>
and then use image insert way to embed the svg file in any other markdown file, like this:
![](./path/example.svg)
As answered by mjgpy3, you can include html - no <html>
tags needed, but it'll be sanitized before display and the only tags allowed are in this whitelist.
The list currently includes:
h1 h2 h3 h4 h5 h6 h7 h8 br b i strong em a pre code img tt div ins del sup sub p ol ul table thead tbody tfoot blockquote dl dt dd kbd q samp var hr ruby rt rp li tr td th s strike summary details caption figure figcaption abbr bdo cite dfn mark small span time wbr
but no iframe
