In Detail

CSS styling has been a key part of developing for the Internet since the early 1990s, but unlike JavaScript, has suffered from the inability to produce dynamic styles, using functions, operators, and variables. SASS uses the power of Ruby to bring support for all three and more to your CSS, allowing you to engage in a more efficient, modular style of working, and making it easier to maintain your CSS styling in your projects.

Instant SASS CSS How-to is a practical, hands-on guide that provides you with a number of clear step-by-step exercises, which will help you take advantage of the power of SASS, and give you a good grounding in writing and compiling CSS style sheets using the SASS pre-processor language.

This book looks at how you can incorporate SASS into your web pages, and either produce style sheets dynamically, or pre-compile them before including the final article into your site’s pages.

You will also learn how you can use the power of mixins, functions, and variables to help produce style sheets, and reduce the amount of code you need to write in your style sheets. We will also take a look at how you can incorporate a more modular style to your development workflow, which will help with making style sheets more manageable and easier to update in the future. We will also take a look at how you can build up libraries of reusable code that you can incorporate into your future projects.

You will learn everything you need to know to start using SASS to help produce more efficient style sheets in your site’s pages, and adopt a more modular development workflow, which will make it easier to maintain your sites in the future.
