skin

(Requires: 3.0)

This option enables you to specify what skin you want to use with your theme. A skin is basically a CSS file that gets loaded from the skins directory inside the theme. The advanced theme that TinyMCE comes with has two skins these are called "default" and "o2k7".

Example of usage of the skin option:

tinyMCE.init({
	...
	theme : "advanced",
	skin : "o2k7"
});
