apply different html templates for differents taxonomy or different module or different block.
natürlich will man das gegenteil, nicht ical/rss-links entfernen, sondern microformate hinzufügen... aber da steht, wie's geht
Eldorado Superfly is a module that takes control of the "Submitted by..." text, node links, user pictures, and comments. It moves them to $node->content, where they can be re-ordered on CCK's Manage Fields tab. However, this means they are no longer under control of the theme.
With this, we have a form at admin/build/themes/settings/myTheme with a checkbox that allows us to enable all module css or disable all module css and a series of checkboxes that lets us selectively turn module css back on when all module css is disabled.
