font-size

How can I increase the my posts font size in my blog www.HobbyAndArt.ru?
I think I must chande CSS style, but I can not find where.

Hi!
You can find styles for tag body in the beggining of style.css. and increase option font-size. Or you can add following code to style.css to increase only post text:

.articles .post-body {
font-size:15px;
}

and specify needed font-size there.

It works! Thank you for your help!
