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.

Vectors or bitmaps/raster images

When people ask what the difference between vectors and bitmaps/raster images is, the answers I often hear are usually around the idea, "If you enlarge it, it won't lose its quality. No worries for mobile devices." Although true, it doesn't fully answer the question. So here are the differences:

A vector image is a file made out of mathematical equations. The results of these equations are represented by a graphic (lines, shapes, colors). If the size of the image changes in any way, the values of those equations are recalculated and the resulting graphic is painted again.

A bitmap or raster image is a file made out of pixels. These pixels have a specific/defined width, height, and color. If an image is enlarged, the pixels...
