Changing Font of posts

Hi. Is there any way to change the default size/font and of post titles. My site http://http://hiphopdaily.comyr.com/. I'm using the "hiphop" theme.

Thanks, any help will be greatly appreciated.

Can anyone help?

Hi!
To fix this you have to edit css --> index.css. You have to edit the code:
.articles .post-body {
font-size: 13px;
line-height: 18px;
}
