Mastering Responsive Web Design

Overview of this book

Building powerful and accessible websites and apps using HTML5 and CSS3 is a must if we want to create memorable experiences for our users. In the ever-changing world of web design and development, being proficient in responsive web design is no longer an option: it is mandatory. Each chapter will take you one step closer to becoming an expert in RWD. Right from the start your skills will be pushed as we introduce you to the power of Sass, the CSS preprocessor, to increase the speed of writing repetitive CSS tasks. We’ll then use simple but meaningful HTML examples, and add ARIA roles to increase accessibility. We’ll also cover when desktop-first or mobile-first approaches are ideal, and strategies to implement a mobile-first approach in your HTML builds. After this we will learn how to use an easily scalable CSS grid or, if you prefer, how to use Flexbox instead. We also cover how to implement images and video in both responsive and responsible ways. Finally, we build a solid and elegant typographic scale, and make sure your messages and communications display correctly with responsive emails.

Chapter 1. Harness the Power of Sass for Responsive Web Design

Before we dive into mastering responsive web design, we need to be on the same page as far as technologies go, in our case, CSS preprocessors and, specifically, Sass.

In this book, all CSS is going to be written in Sass in SCSS format. The way we write CSS has changed; it has improved tremendously.

CSS preprocessors such as Sass, LESS, and Stylus give the web/mobile designers and developers new superpowers. Yes, I used the word superpowers because that's exactly how I felt only a few hours after using Sass for the first time, and what I used was as basic as it gets:

.navigation-bar {
    display: flex;
    li {
        padding: 5px 10px;
    }
}

See the nested li selector? Yeah, that's Sass in action. When the preceding code is compiled, this is what it looks like:

.navigation-bar {
   display: flex; 
}
.navigation-bar li {
   padding: 5px 10px;
}
