Well, erm...
Maybe I have the terminology wrong. XD
But, what I am asking for is:
Some sites don't let you edit everything. So, an overlay is kind of a way to cheat, and post a picture or something along those lines "over" the existing webpage. Then, from there you can kind of go from there.
Right now, I am just trying to do a simple one, something for... myspace. Mainly for a learning experience with using CSS and HTML. As for I am still learning how to use them together...
EDIT:
Here is a stylesheet for an Overlay...
<style type="text/css">
.Main { position:absolute; left:50%; top:125px; width:800px; z-index:1; margin-left:-400px; padding:0px; border:0px; background-color:transparent; background-image:url("http://xs60.xs.to/pics/05516/blackandwhiteback.png "); color:000000; font-size:12pt; background-color: ;}
.Scrollbox { overflow:auto;width:450px;height:300px; color:000000; font-size:12pt; font-family:sylfaen; background-color: ; background-image: url(); border:2px solid black;}
.comments { width:10px; height:10px; overflow:auto; }
.player { position:absolute; left:0px; width:300; top:500 }
/* Navbar */
body div div table td { visibility: }
.navibar {background-color: white !important; position: absolute; left:50%; top:0px; margin-left: -400px; width: 800px; height: 153px; }
.nav { color:000000 !important; font-family:arial !important; }
/* Background Codes */
