Just a sets of theme so you dont have to choose for the font, font sizes, color, bgcolor and so on...
Ok assuming that i have the following rules in the "black.css"
body {
borderd: none;
backgroud-color: #000;
color: #ccc;
font: normal 12pt/105% Georgia, Arial, sans-serif;
}
You can provide themes as many as you want. The ones you use depends only on your design capabilities and imagination.
