I suspect that I could use a primer or help with understanding how it is employed, if it is indeed how the following effect is achieved...
For example, look at this site... http://www.heidi-strobel.com/html/index.html
When I copy the site code and load it up in a HTML editor ... all I get is the html elements occuring below the graphic... versus "in front" of the graphic.
Why ?? what's going on with this?
