Help with tumblr

[popki]

Okay so I purchased the savory theme on tumblr.

http://savorytheme.tumblr.com/

And I'm trying to change the description title font (located here: http://i53.tinypic.com/35lvkao.jpg)

I want my description title aka 'quote' on my website to look like this:

http://i55.tinypic.com/f50h7c.jpg

Basically, I want the author of the quote to be below the actual quote and in smaller font.

I tried contacting the theme's creator but have not heard back. I'm needing the code to customize it and put it in the advance section of my theme.

So far I have this in my advance section: aside section.description h4 { text-center: right; font-size: 12px;}

Anybody that can help?
