Forum:Third-level Heading Underlines

I have this strange happening where sometimes my third level headings ( ===text=== ) get underlined, and sometimes they don't. You can see an example of this in action on this page. Anyone know what's going on? It's probably something in the CSS I'm missing, but I can't figure out what it is. (What I'd like to have happen is have third-level headings underlined all the time.)

 * It might just be me overlooking it (it's a long page), but all the h3's I see are in fact underlined. 22:33, January 13, 2010 (UTC)


 * Same here. -- Porter21 (talk) 23:38, January 13, 2010 (UTC)


 * Using Firebug (or IE8 dev tools) we can understand that you putted the underline (bottom-border) on element of class "mw-headline".
 * You should only redefine the "h3" tag style. — TulipVorlax 00:26, January 14, 2010 (UTC)


 * Weird, everything looks underlined from my browser at home (newest Firefox), but at work it does not (older Firefox). So basically, you're saying I should put h3 { bottom-border: whatever; }, and delete .mw-headline? Surgo 04:36, January 14, 2010 (UTC)
