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.

Preface

Sizing our headings


Let's move on to adjusting our headings font sizes, and then we'll move away from vertical rhythm. To adjust our heading sizes, we'll need to let Compass know we want to adjust their size in relation to the vertical rhythm we've defined. For this, we use the adjust-font-size-to mixin.

We'll also want to use the default heading sizes from the last chapter. However, this time we'll be multiplying them by our $base-font-size variable in order to get the pixel value. Remember, Compass uses pixels in all of its vertical rhythm mixins. So let's create a list with our heading sizes so we can loop through it to create our headings:

// mastering-sass/ch03/scss/screen.scss 
$base-heading-sizes: (2, 1.5, 1.17, 1, 0.83, 0.67); 

Now we can loop through each of items in this list and create all of our headings by multiplying the values by our $base-font-size, which will give us the pixel values for each heading:

// mastering-sass/ch03/scss/screen.scss 
@for $i from 1 through...
