Overview of this book

CSS and Sass add elegance and excellence to the basic language, and consist of a CSS-compatible syntax that allows you to use variables, nested rules, mixins, inline imports, and much more. This book will start with an overview of the features in Sass and Compass, most of which you'll already be familiar; however, this will ensure you know what’s expected as the book goes deeper into Sass and Compass. Next you will learn CSS and HTML concepts that are vital to a good Sass workflow. After all, Sass exists to simplify writing CSS, but it won’t teach you how to make clean, scalable, reusable CSS. For that, you need to understand some basic concepts of OOCSS, SMACCS, and Atomic Design. Once you’ve brushed up on the important concepts, it’s time to write some Sass. Mainly you’ll write a few functions and mixins that really leverage control flow using @if / @else loops and you’ll learn how to figure out when and why things are going wrong before they bring you to a stop. Moving further, you’ll learn how to use @debug, @warn and @error to properly handle errors. You’ll also learn about Gulp and how to use it to automate your workflow and reduce your repetitive tasks. And finally you’ll learn about sourcemaps. With sourcemaps, you’ll be able to write, debug, and view your Sass and Compass all from within the browser. It’ll even LiveReload too! As a bonus, you’ll take a look at that funky Flexbox, currently all the rage! You’ll learn how powerful and flexible it really is, and how you can use it with Compass. Best of all, it falls back very gracefully indeed! In fact, you’ll be able to apply it to any existing project without having to change a line of the original CSS.

Chapter 5. Advanced Sass

In this chapter we'll look at some of the more advanced features of Sass. We'll take a comprehensive look at variables and in particular variable scope and using the !default and !global flags. We'll look at the problems which can arise when using local and global scope in mixins, functions, and selectors.

Then we'll look at creating a mixin which generates pure CSS arrows. To create this mixin we'll need to use extends and interpolation to dynamically use those extends from within our mixin. We'll also see how we can simplify checking for multiple values within an if statement using the index function.

We'll then create a mixin which will simplify writing media queries. We'll use the @content directive which allows us to pass additional properties, mixins, or extends to a mixin.

Lastly, we'll look at using maps. Maps will allow us to group similar variables into a key value set. We'll look at how to retrieve...
