Pandoc MD to PDF , full size horizontal rule

Question

I'm using pandoc (on windows with miktex)

with markdown i create a horizontal rule, save that as my source.md

---

(or even an hr tag instead)

but when I convert to PDF the horizontal rule is a tiny little line in the middle of the page, centered.

How do I get it to create one from margin to margin like it does when I convert it to HTML?

Edit:

I tried a CSS styled DIV tag that creates a rule but it is completely ignored during a pdf output.

Answer 1

As pointed above, you can redefine the \rule command in your custom LaTeX template to ignore the first argument:

\let\OldRule\rule
\renewcommand{\rule}[2]{\OldRule{\linewidth}{#2}}
