Float a div above page content

give z-index:-1 to flash and give z-index:100 to div..

Use

position: absolute;
top: ...px;
left: ...px;

To position the div. Make sure it doesn't have a parent tag with position: relative;

You want to use absolute positioning.

An absolute position element is positioned relative to the first parent element that has a position other than static. If no such element is found, the containing block is html

For instance :

.yourDiv{
  position:absolute;
  top: 123px;
}

To get it to work, the parent needs to be relative (position:relative)

In your case this should do the trick:

.suggestionsBox{position:absolute; top:40px;}
#specific_locations_add{position:relative;}
