Stylesheet changer

A basic example on how to change your stylesheet dynamicaly! I will use a dropDown list to control the environtment!
Assuming that you have 4 different .css ( default, red, blue and green ) on your directory!

From this line you'll have to replace this with your own stylesheets.

default.css
body{ background-color: white; color: black; } red.css!
body { background-color: red; color: black; } blue.css!
body { background-color: blue; color: yellow; } green.css
body { background-color: green; color: white; }
