A PlayerPal skin:
A PlayerPal skin is made up of Views and Panels. These are conceptual terms. A View appears to you as a page in the skin that you see in your web browser. You can see the view you are looking at in the PlayerPal page URL. For example http://localhost:9999/default.aspx?view=DefaultView. In this case DefaultView is a file called DefaultView.ascx in the skin folder.
A Panel is a chunk of common code that appears in one or more Views. The contents of a panel are same as that of a View. They are just thought of differently as they are included in multiple Views. A good example is the common header and footer that appears on every page in the PDAClassic skin.
PlayerPal has a number of widgets that you can include in your Views and Panels. These widgets provide the functionality that PlayerPal provides. For example there is PlayButton widget that you can include to provide the Play and Pause functionality in your skin.
Put all these together, add some magic CSS fairy dust and you have a beautiful skin page.
