If a frontmatter is present, it will not be rendered:

---

But if a frontmatter doesn't happen on the first line, it will be parse as regular Markdown content

This is a text1
---
this: is a frontmatter
---
This is a text2
.
<h2>This is a text1</h2>
<h2>this: is a frontmatter</h2>
<p>This is a text2</p>

It expects an exact 3 dashes ---:

----
this: is a frontmatter
----

It can end with three dots ...:

---
this: is a frontmatter

...
This is a text
.
<p>This is a text</p>

If the end front matter marker (... or ---) is not present, it will render the --- has a <hr>:

---

This is a text</p>

It expects exactly three dots ...:

---
this: is a frontmatter
....
This is a text
.
<hr />
