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.

Stop using CSS grids, use Flexbox!

I bet you didn't see this one coming, ha!

Indeed, Flexbox is one amazing CSS property that opens the layout possibilities to new horizons. Here are a few things about Flexbox:

  • Its browser support is perfect in modern browsers.

  • IE8 and IE9 don't support it. But no worries, addressing these two browsers is very simple using the conditional classes technique mentioned in Chapter 3, Mobile-first or Desktop-first?

  • IE10 only supports the 2012 syntax, but Autoprefixer (within Prepros) takes care of this old vendor prefixing automatically for us.

  • We need to be careful when using Flexbox because the old display: box; syntax causes the browser to do a multi-pass in the layout, deteriorating the performance.

  • In contrast, the new/current syntax display: flex; has no impact on performance whatsoever. Browser performance issues have now been addressed since the old syntax, so we should be in good shape.


Paul Irish and Ojan Vafai explain this very well in the post Flexbox...
