The Mac Dashboard is an application for Apple’s Mac OS X operating systems, and is used for hosting mini-applications known as widgets. It was first introduced in Tiger, and is a semi-transparent layer that is invisible to the user unless it is activated by clicking its icon in the Dock.
Dashboard widgets for Mac OSX are created using Hypertext Markup Language (HTML), Cascading Style Sheets (CSS) and JavaScript.
Since the same languages are used for creating websites, many web developers can already build them to their specifications and task related needs.
Bottom line, Widgets themselves are, simply HTML files that are displayed within the Dashboard layer; they use the WebKit application framework that is also used in Apple’s Safari web browser, meaning even users running earlier versions of Mac OS X — where the Mac Dashboard is unavailable — can build them.
