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.

Regardless of which techniques we use, we are going to have to use a desktop-first approach since the site we're dealing with was built for wide screens only. This means that we're going to use the max-width property in our media queries.

Before we look at both retrofitting techniques, we need a base page to start with.

The base page

The graphic you see here is proportional to a 12-column 980GS layout. The browser window is 1024px wide and the page is 980px wide:


Our main container in gray, which is 980px wide, already has 10px padding to the left and right. This means...
