How do I make the font of "Leave a Reply" smaller? The site I'm working on is: masaueharadesign.com. I'm practicing WordPress there.

When you click on "Canine and feline medicine" under Recent Posts on the right side bar, you come to a post with a comment box (in the center, main column). Above the box, there are two bold lines:
"1 Comment to Canine and Feline medicine" and "Leave a Reply". I'd like to reduce the font size of the two lines.

Will you please tell me how I do that? Thank you very much for your help.

Add a CSS Insert

h3#comments {
font-size: 1.2em;
}

Also, something is wrong with your Site Admin -> Settings -> Permalinks

Remove the /blogs/ from your settings there

Comments headline font got smaller with the above CSS insert. Thank you, Flynn! "Leave a Reply" above the comment box did not change though. Will you please tell me how to make that font smaller? Thank you.

Add CSS Insert

h3.reply {
..
}

You can find these out by looking into the source code of a browser rendered page, or by using firebug.

Something with a class, such as <h3 class="reply">....</h3> can be changed with

h3.reply {...}

Something with an ID, such as <div id="some-id">...</div> can be changed with

div#some-id {...}

For elements with classes:
selector-name[DOT]class-name { property: value; property: value; property: value; }

For elements with ID's:
selector-name[HASH-SIGN]id-name { property: value; property: value; property: value; }

Thank you very much Flynn! I got it. I understand! Resolved.
