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.

Why aren't you using HSL?


What if I asked you "what is the hex code for yellow in CSS?" It's #ff0. Now I don't know if you knew that or not, but let's keep going. What is the hex code for purple? What is the hex code for green? What is the hex code for red? How many of those did you know off by heart? Probably not a whole lot, if any. When it comes to hex color codes, I know what black and white is and then things quickly move towards needing a color picker of some kind. Just FYI, purple is #7f00ff, green is #0f0, and red is #f00.

What if I said you can use the RGB model? With a bit of color theory, you could figure out all of those colors without needing anything else. Let's start with red. Well that's easy! RGB stands for Red, Green, Blue. We know 255 is 100% of that color, so red is RGB(255, 0, 0). Green would be RGB(0, 255, 0) and blue RGB(0, 0, 255).

So what is yellow? Ok, yellow is an equal mix of red and green. So 1 to 1 of red and green, therefore yellow is RGB(255, 255, 0). What about...
