Yes I understood it a few minutes after posting..
However, tricking FCKeditor is a pain.
I’ll look for tinymce. So boring, directions writing in the manager (site conf, edditor..) are not true ..
for FCkeditor, needs to enter manualy à whole list of stuff into an xml file. and doing the job twice (or more is not my goal)
Tinymce is supposed to acces an external css (normal way from my point o view) but dont seams to be enough, I ’m on my way to deal with this. So I’ll post later something else,. I guess this thread could be close
Thank you
