To can center a fixed or absolute positioned element (Div or other block element), set the right and left CSS properties to 0, and then margin-left and margin-right to auto, as if you were centering a static positioned element.
- Example, centering a fixed Div:
<style type="text/css">
#divid {
  position: fixed;
  /* center the element */
  right: 0;
  left: 0;
  margin-right: auto;
  margin-left: auto;
  /* give it dimensions */
  min-height: 8em;
  width: 90%;
  background: #dafeda;
}
</style>

<div id="divid">http://CoursesWeb.net/</div>
- Example, centering an absolute positioned Div (the parent element must have: position: relative):
<style type="text/css">
#parent{
 position:relative;
 height:8.5em;
}
#divid {
  position: absolute;
  /* center the element */
  right: 0;
  left: 0;
  margin-right: auto;
  margin-left: auto;
  /* give it dimensions */
  min-height: 8em;
  width: 90%;
  background: #dafeda;
}
</style>

<div id="parent">
  <div id="divid">http://www.MarPlo.net/jocuri/</div>
</div>
