I have tried successfully the FileLibrary but I want to be able to modify the stylesheet without using Pharo which will be running on a remote server. Using static documents seemed the solution to me.

The easiest way is to use a Seaside FileLibrary subclass to serve your static CSS file. This is described in that same chapter 17.
