Confluence 6 - collapse sidebar permanently for a space

[DG COMP]

Hello, we would like to collapse the sidebar permanently for a space in Confluence 6.

We manage to hide the contents of the sidebar for a space with following code in Space / Look & Feel / StyleSheet:

.acs-side-bar
{  display:none !important; }

Do you know if something similar exists to collapse the sidebar ?

I too am looking for the same thing. Or at the very least to have the sidebar collapsed by deafult
