To signal a thematic break, you can specify a horizontal rule.
This is done by entering at least three hyphen-minus characters (""''-''"", U+002D) at the first position of a line.
You can add some [[attributes|00001007050000]], although the horizontal rule does not support the default attribute.
Any other characters in this line will be ignored.

If you do not enter the three hyphen-minus character at the very first position of a line, the are interpreted as [[inline elements|00001007040000]], typically as an \"\"en-dash" followed by a hyphen-minus.

Example:
```{="zmk"}
---
----{.zs-deprecated}
-----
 --- inline
--- ignored
```
is rendered in HTML as
:::{="example"}
---
---{class="zs-deprecated"}
---
–- inline
