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

Setting up Source Maps in Chrome


To set up source map support in Chrome you will first need to check if support is enabled. Open up the Chrome DevTools. You can do this with Ctrl + Shift + I / Cmd + Shift + I or right click anywhere on the current page and select Inspect (or just press F12). From here you will need to navigate to Settings. The easiest way to get to the settings is just to press F1 while the DevTools are open. Otherwise, to find the DevTools settings, look for an icon of three dots at the top right of your DevTools (sometimes jokingly called a Kebab menu icon, brother to the Hamburger menu icon). From there you'll see settings.

From here you'll need to make sure Enable CSS source maps and Auto-reload generated CSS are checked under the Sources section of the General tab.

Close settings, and while on the Elements panel select the <h1>...</h1> element. Beside the styles for the h1 element you'll see style.css:1. Click this to be brought to the Sources panel...
