I'm trying to cange the type size for 'Leave a Reply'. I know this has been covered before but it's not working for me.
I'm using 3.6.4 and have tried the footer box and inserting this into CSS Inserts

h3.reply {
font-size: 12px;
}

URL: http://www.musictherapymatters.com/?p=1#comment-2

Nothing changes.

Firebug 1.6 not picking up CSS on this URL.

this should work id think:

h3#reply-title {
font-size: 12px;
}
