You are on the right track: if you want to do it like that (which is very clean, congratulations!) you have to modify all the remaining parts of the pagedown::html_resume() stylesheet; in other words, you cannot just add this declaration, this is not sufficient.
You have two options:
- write a new clean stylesheet which would implement a sidebar only on the first page
- use one of these quick and dirty hacks. They work well
