Basic CSS Question

[Whigga Spitta]

I am currently modifying a wordpress theme to use as a blog/portfolio site. I have it looking almost like I want it to, although there is a certain element I'd love to have.

There is a little gray horizontal bar at the top of the following page, although when searching google for CSS tutorials/tricks, I didn't really know how to explain it, so I'll try my luck here:

I don't really know a thing about CSS, so any help regarding what it is (a DIV tag I'm guessing?) and where to put it would be greatly appreciated.

the top bar is... in this...

body
{
    margin: 0;
    padding: 0;
    font-size: 62.5%;
    font-family: "Helvetica Neue", Helvetica, Verdana, Arial, sans-serif;
    [COLOR="Red"]border-top: 1.0em solid #ccc;[/COLOR]
}

Wow, thank you very much for the quick reply. I guess I knew where to look for the code although I didn't know what to look for. Thanks again.
