How to adjust the width of the exported PDF

[LumenYoung]

Hi, everyone,

I've been using this theme for a long time and I think this is the most elegant theme on obsidian IMO. But I've tried several ways to adjust the width of my exported PDF. for example @page in the customized CSS. But none of them can let me adjust the width.

I would like to ask if anyone know how to solve this. Because I'm not using sidenote (I would really like to give it a try but I don't know yet how to use it) so the margin is a bit wasting for me.

Anyway, hope this theme can gain more attention!
