Ok, sure, here is my file :

I would love not to do it "by hand" but I don't know how to do it in an other way : "my" Calibre doesn't purposes me to edit the books (it just makes the conversion), and I did mine with word (conversion to html) and then RJ textedit where I put the css in an other file, and create the content.opf and the toc.ncx... But if you know a software or have a better solution, of course I take it !
Thanks for your support.
