How to decrease font of sidebar?

[lyrk]

I need to decrease font in sidebar. Is there a custom snippet for this?

You can make it tighter, see (will possibly bring it into the OP of the topic)

[Wiki] CSS snippets to make things more compact and minimal

Tighter sidebar, courtesy of @steveaw . 0 may be a bit too severe, try 1 px as well. /* tighter sidebar */ #document-sidebar div { padding-top: 0px; padding-bottom: 0px; }
