Embedded blog into website, how to change fonts?

I have a self-hosted WP blog at mijawo.com/blog. I just finished embedding the blog onto the main index.php page of my site. I cannot figure out how to edit the font/size of the posted text on this main page. Can someone point me in the right direction?

I tried logging in as the admin through my blog and messing with the templates there, but I don’t think this is directly connected with the embedded text.

My website is: http://www.mijawo.com

Thanks for any information you can provide!
