Font Size

Hi everyone,

please forgive me if I don't know proper etiquette and such for asking questions on a forum. I've never done this before. Usually I can figure things out for myself.

My question is regarding the middle-earth theme which I purchased (and is great btw)

I'm looking to increase the standard font size a little bit for the main body content. (what you see on my site for now, I've increased manually with each post)

I can't find where in the CSS file to make the change. And how should the code look? I'm thinking something about 1.5em or 15px or so is what I want.

Do I need to post the CSS file? or is a link to my site sufficient for someone to help? www.thekreggorian.com

Any help is much appreciated. Oh, and don't be too critical of the site, it's still under construction. lol

Thanks in advance!

If any one other wants to know that, it's

.articles .post-body {
font-size: 13px;
line-height: 18px;
}

in the index.css.
