Written by Sass and Compass creators * Complete Sass language reference * Covers prominent Compass community plug-ins * Innovative approach to creating stylesheets Cascading Style Sheets paint the web as the user sees it and for years the web has been painted by hand. Sass and Compass extend standard CSS to give more flexibility and the option to simplify or automate many tedious tasks. Sass and Compass are the power tools that allow stylesheet authors to "paint" with remarkable speed and precision. Sass and Compass in Action is the definitive guide to stylesheet authoring. The book begins with simple topics such as CSS resets and moves on to more involved topics such as grid frameworks and CSS3 vendor implementation differences. Then it culminates in a step-by-step look at building a personal stylesheet framework in which readers can bundle their own approaches and opinions and reuse them across projects.
