Reducing the title size of the Blog Category layout

Hi all, I would like to reduce the title of each article in the blog layout. I would like to reduce it by say 20% but when I find this font in the css and reduce it - it seems to effect other areas. Can someone point me to the right place to change these titles here on this page: http://www.jamjodesign.com/sandpit/marl ... eases.html

Thanks in advance.

To answer my own question and for others its here: /templates/gk_appsite/css/joomla.css

.contentheading (line 97)

{

font-size: 45px;

color: #333333;

font-weight: normal;

}

change the font-size in this file and your done
