Z-Index is a CSS setting that determines the stacking of different elements in a browser window.  A higher z-indes means the element is closer to the person viewing the page (further away from the base of the screen)

There is a video at https://www.youtube.com/watch?v=vo5Aw2WJlZ4 which shows you how to do this in DreamWeaver, and a more detailed description of how z-index works at http://webdesign.tutsplus.com/articles/what-you-may-not-know-about-the-z-index-property--webdesign-16892.  If you search Google for "css z-index" there are also MANY other tutorials out there, but they are not all easy to understand.

The way to put one on top of the other is to give the parent container a position:relative and give child div's a position:absolute and then use top and left to position them
<div style="position:relative">
<div style="position:absolute;top:10px;left:10px"></div>
<div style="position:absolute;top:0;left:0"></div>
</div>

Open in new window

Hi yes thank you for the explenation. Do you have any explenation of the position property: absolute, relative and fixed and static. Peter

position:absolute means whatever left and top settings you set position the element at those coordinates relative to the nearest relatively positioned element

If no relative positioned elements then it will be relative to the browser window
