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, 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, typically as an ""en-dash" followed by a hyphen-minus.
Example:
---
----{.zs-deprecated}
-----
--- inline
--- ignoredis rendered in HTML as
–- inline
