is it possible to change page's width according to the type of page?
I started from the default template. In wiki reading mode, I have a design that I like (80ch width on the article part). But there are types of pages where I would like a different rendering.
For example, when I display the differences between two versions, I would like use the entire width of the screen (100%). Or on the administration options, the width can also be larger than my base width.
I can't find a way to have different css rules for this type of page. Everything seems to be contained in the php "<?php tpl_content() ?>" and I can't change much about it. Have you idea how I can change this ?
