Working with the Theme Skin Manager
The Theme Skin Manager lets you preview and manage the skins associated with the active theme on your domain. A skin is a group of elements that are designed to compliment each other. You can preview each of the skins that come with the theme. You can also copy any of the default skins to reference and activate later. Additionally, you can customize any of the copied skins. This lets you keep the overall look and feel of the theme, while applying skins when needed.
