the font size for my blog content is too small

Hi,

I'm hoping someone here can help me please

No matter what I try, I cant seem to increase to font size of easyblog on the front page

I've tried changing in the editor section and it's fine on the second page when you click into an article but no change on the home page.

Anybody have any ideas what the issue might be please? My website link is below
