## 9.5 Write raw content (*)

The technique introduced in Section 6.11 is actually a general technique. You can protect any complex raw content in Markdown by specifying the content as “raw.” For example, if you want to write raw HTML content, you can use the attribute =html:

{=html}
<p>Any <strong>raw</strong> HTML content works here.
For example, here is a Youtube video:</p>

<iframe width="100%" height="400"

{r}
