Mastering Responsive Web Design

By: Ricardo Zea

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.

I can use SVG instead, but IE8 and below don't support SVG. I can use icon fonts, but what happens if the icon font doesn't load? I'm going to have to look up some analytics then. There's a new iDevice with a new type of high-density screen? Now I have to export two (or more) images every single time. Great! But I can't serve a high-quality image that's more than double the size of the regular size image to small-screen devices! Yeah, it may look good but it'll take forever to download, they just might as well leave the site even before the first H1 loads.

You get the picture. That's barely scratching the surface of...
