[Mediawiki-l] use additional css in extension

[Lars Drögemüller]

Hi,
I made an extension, which does some syntax highlighting. I'd like to 
use an extra css file, so determine how the highlighted code will show 
up, and to use the class-attribute to color the code.
Where am I supposed to write the style definitions? When I put them 
right into the extensions php file with a style-tag, it screwed up the 
font-size of the whole wiki page.
Any Ideas?
