Will it be possible to have a list of all variables that can be changed using css, to change the format of the publication list ?
CSS is actually self-documenting. Just open the source of the page you are editing, look for the elements you want to modify, and find a unique selector for them (e.g., using their class and/or tag name). This is actually not a BibBase specific question, so you should be able to find more help on that on the web.
