"Pragmatic Guide to Sass is edited by Kay Keppler and offers a fine guide to Sass, a language similar to CSS but with more extra power and enhancements. With Sass you can modify colors, calculate layouts and much more. The program offers a fine method of writing maintainable CSS and covers all of Sass's features, from variables and mixins to using Blueprint. Packed with plenty of code examples, this is a primer that shouldn't be missed."
