Positioning a “wrapper” div underneath a fixed navigation bar?

Question

I\'ve started work on a brand new site and i\'ve been playing around with designs for a while, however one problem I seem to be having is regarding positioning a navigation

Answer 1

set top:0 on your navbar and add 30px margin-top on your wrapper div

#navBar {
    background: RGB(0, 0, 0);
    height: 30px;
    position: fixed;
    width: 100%;
    top:0
}
#wrapper {
    margin: 30px auto 0;
    width: 980px;
}
