How can I make a div go on top of another div?

Do you see that changing text? I want to move that div up to the header image right under the navigation bar.

I know it has something to do with absolute positioning, or z-axis.

If it is a simple thing to do, please help, thanks.

actually, i need to revise that question.

although the div is now moved up, the space where it was originally is still there, pushing the "welcome" image down. how would i get rid of that space?

try this css instead

#contentwrapper {
    color: #FFFFFF;
    font-family: arial;
    font-size: 14px;
    height: 25px;
    left: 25px;
    margin-bottom: 0;
    margin-left: 25px;
    margin-right: 25px;
    margin-top: -42px;
    position: relative;
    width: 800px;
}
