Hello. I use the last version of MediaWiki and timeless thememe. When I start a new line (br) i got a really big interval between lines like for a new paragraph. I want to change it for a normal (if i wouldn't press "enter" and it was the same line).

I've found to edit common.css but I didn't find this file. Where should I put this file and what should i put inside that file? Something like p {margin:bottom 0.1em}?

so paragraph (what happens if you hit newline twice in a row) and br tags are different. The css you mentioned would be for a p (paragraph) tag.

I know that, it was just an example. Anyway it doesn't work.
