How do I make the nav bar always at the top?

I have no idea what those 2 things are, but this is how you fix something in place regardless of window scroll position with CSS:

#navbar {
    position: fixed;
    top: 0px;
    width: 100%;
}​

See here: http://jsfiddle.net/qC2Dt/

If you're using foundations, you can use:

<nav class="top-bar fixed"></nav>
