Markdown does not support the use of iframes

朱礼程

 I have incorporated a markdown plugin, but the iframe does not work as intended（CommonMark Spec）. The markdown code I am using is:

 

```

<iframe src=<span>"<a href="https://www.bing.com" rel="noopener nofollow noreferrer" target="_blank">https://www.example.com</a>"</span> width=<span>"800"</span> height=<span>"600"</span>></iframe>

```

Please note that Markdown plugins may have varying support for iframes, and it is important to refer to the relevant documentation or specifications for proper usage."
