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.

Using the Modular Scale for typography

If you click on the Table view, all the text is now gone and we're left with a list of font sizes—ranging from ridiculously small values to just as ridiculously large values. But that's ok. That's the power of a modular scale.

This is what we see:

As you can see in the preceding image, there are three columns:

  • The first column shows the font size in pixels.

  • The second column shows the font size in ems.

  • The third column shows the font size if the base was 16px.

What we need to do is focus on the first and second columns only. The highlighted row that says 16px, or 1em, is going to be the font size of our paragraphs. 16px is the default font size in most browsers.

Then, we define our header elements. Let's say we define only h1, h2 and h3. This means that we're going to select the rows above 16px that have larger font sizes:

  • <h1>: 39.269px that is 2.454em

  • <h2>: 25.888px that is 1.618em

  • <h3>: 24.57px that is 1.517em

For the <small> element...
