So now that you have the menu bar all laid out, you can hook it up to some script and make it useful. The first thing you should do is take the moreMenu class and turn off its visibility. Most menus aren't active and visible when the window comes up initially. So you should change the class selector to read:
.moreMenu {position: absolute;
width: 100px;
border: 1px solid red;
background-color: red;
layer-background-color: red;
visibility: hidden;
top: 22px;
}
So while the DIV is still there on the page, it has been rendered invisible by the browser.
