change margin for individual pages

[besendorf]

Hi,

I have a markdown file that I convert to pdf with this template. One page is in landscape mode. I did it like in the example with this in the header

header-includes:
- |
  {=latex}
  \usepackage{pdflscape}
  pandoc-latex-environment:
  landscape: [landscape]

and this where I want landscape layout

::: landscape
\thispagestyle{empty}

:::

I also removed footer and header with \thispagestype{empty} to make even more room widthwise. However the margin is still pretty big. How can I change it for only this section or this individual page? I tried a few option like setting landscape: [landscape, margin=2cm] and others but they either didnt work or they rendered the landscape page vertically.

remove \. I did not know how to escape those in github markdown
