To signal a thematic break, you can specify a horizontal rule.
This is done by entering at least three hyphen-minus characters (&ldquo;`-`&rdquo;, 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, they are interpreted as [inline elements](00001007040000), typically as an &ldquo;en-dash&rdquo; followed by a hyphen-minus.

Example:

    ---
    ----{.zs-deprecated}
    -----
     --- inline
    --- ignored
