How do I disable Atlassian header from a single Confluence page, say "404.vm" - "Page Not Found" error page.

I don't want to implement this for all pages but just one page

How do I disable Atlassian header from a specific Confluence page say "404.vm" - "Page Not Found" error page.

I tried
#header

{display:none;}

on 404.vm but that didnt work however when I apply that to General Admin --> Layout --> Stylesheet, it works

But i only want to implement this to just one Confluence page - "404.vm"
