Change font style in News & Info Center

[transoxiana]

How do I change the font style - STYLE, not size - in these categories? News and Info Center? In every other category, I have managed to change it, but it doesn't include those two - I don't know why.
Can anybody help me?

Are you talking about a V4 forum or a V5 (looks like this site)? A link to your site would have answered that question.
Are you trying to change the titles or the text within the info center? If your forum is still a V4 fourm, for the titles: forum statistics, uses online, active users the class for that is .cattext and for the title Info Center the class is .text1 so you could put something like this in your global header:

<style type="text/css">
.cattext{
font-family: tahoma;
}
.text1{
font-family: tahoma;
}
</style>

.cattext is for all the categories titles.
