[Mediawiki-l] lay-out buttons in edit pages

[Rein]

Thank you, Dr JFBurté, very much.
Some notes for others who want the same AND a question on lay-out of the buttons.

You can find the script for common.js at [[Mediawiki:Edittools.js]]
You need three things as well: a line in LocalSettings (don't forget to make the extra directory) and 2 php extensions.
You can find those at:

My question.
For the lay-out of the buttons I need the following css:
class="my-buttons" 
and
class="specialbasic"
In which css file should they be placed?
