How to style font size in comments?
 

I did search for this but couldn't find it. After the switch to Atahualpa 3.4.3, the font size of the comments is just too small. I can't find where to change that, and when I tried to do it with a CSS insert, it didn't work.

For the whole text

ul.commentlist li { font-size: 12px; }

Author name: ul.commentlist div.comment-author { ... }
Date & "Reply": ul.commentlist div.comment-meta { ... }
Just the "Reply": ul.commentlist div.comment-meta span.comment-reply-link { ... }
Comment body text: ul.commentlist p { ... }
