Edit title size and font for blog posts in single category display format

Hi,

I have the EasyBlog single category module running on our website. EasyBlog is working great except that I cannot figure out how to change the blog post titles and make them a different and smaller font. I have tried to edit a number of css files including adding a line to the template custom.css but so far no luck.

It is taking either the h1 or h2 font from my website template and it is too large and the line height is not set high enough. I would like to change it to a smaller font and possibly an Open Sans font.

Any help is greatly appreciated.

Thanks!
Scott
