CSS can get quite complicated too, and with ever more demanding web designs the stylesheets grow longer and more elaborate. Sass (short for Syntactically Awesome Stylesheets) offers a solution: with variables and nested rules, for example, writing CSS becomes a lot easier.

To make getting started and working with Sass easier, Dan Cederholm (founder of Dribbble, blogging at SimpleBits) has written an easy to follow guide with tips and tricks in his new A Book Apart book “Sass for Web Designers”.

For everyone who has not dared to try Sass yet, or has not worked with it much, the book’s appealing layout and relaxed, easy language make a great introduction. If you want to start right away, the ebook is 9 US dollars, and there is also a very nice bound edition for 18 US dollars plus shipping.
