The sheer success of Apple's iPod has unleashed a series of creative uses of the product, including its use as a reference guide.
Web designers may finally be able to justify buying an iPod as a business expense, with the debut of an iPod ready edition of the Westiv Complete CSS (Cascading Style Sheets) Guide.
This guide offers, "a handy overview of CSS concepts, and in-depth onformation for every selector, property and @rule of CSS 2.1". The company claims the guide to be a "must-have" item for "any Web developer with an iPod".
Since 1998, the Westciv CSS Guide has been used by many developers to learn CSS and as a detailed reference guide.
A variety of online tutorials are also available for download.
