You can link a comment - for doing this you need to obtain its url:

About syntax-highlighting on the main site TeX-LaTeX StackExchange:

Just turn off syntax-highlighting:

```lang-none
...
```

In code-blocks of pattern <pre><code>...</code></pre> on the main-site syntax-highlighting currently prevents the displaying of one's own highlighting via HTML-tags like <i>...</i>, <b>...</b>, <sub>..</sub>, etc.

To have your own highlighting via HTML-tags, you can disable syntax-highlighting for a single block of code like this:

<!-- language-all: lang-none -->
<pre><code>...</code></pre>
<!-- language-all: lang-latex -->
