Introduction xxi
Chapter 11 introduces CSS gradients, a method of transitioning
between two or more colors to make unique background decorations.
Chapters 12 and 13 show how to visually transform elements, changing
their appearance in two and three dimensions.
Chapter 14 introduces animation, such as transitional changes between
two values and complex timed animations.
Chapter 15 covers Flexbox, a new way of laying out elements based on
the space available.
Chapter 16 is also about page layout, covering new value units and how
to perform dimension calculations and size elements based on their
contents.
Chapter 17 is the last of the layout chapters, introducing the new CSS
Grid Layout Module.
Chapter 18 looks at visual effects, such as blending an element’s back-
ground layers or blending one element with another, using graphical
filters, and how to clip an element using simple shapes.
Chapter 19 closes the book with a look to the (possible) future of CSS:
new properties and features that are currently fairly experimental but
may become fully implemented across browsers at a later date.
The appendices and further resources
There are two appendices at the end of the book. The first is a quick refer-
ence to the browser support of the CSS features discussed in this book,
and the second is a list of online resources, useful tools, and interesting
demonstrations.
In addition, on the website for this book at http://www.thebookofcss3.com/
you’ll find up-to-date versions of both appendices and all examples and dem-
onstrations used in this book. And if I’ve made any mistakes, you’ll find a
full list of errata there, too.
In addition to the accompanying website, you’ll find more of my writ-
ing about CSS3 (and other emerging web technologies) at my blog, Broken
Links (http://www.broken-links.com/). Feel free to comment or get in touch
with me through either of these websites.
Introduction to the Second Edition .xxi
I began work on the first edition of this book in 2010. It’s been only four
years, but how the landscape has changed in that time! In 2010, the iPad
had been out for only a few months, Android had yet to explode, and look-
ing at visitor statistics for my own website, visits from all mobile devices
accounted for 11.6 percent of sessions—compare that to the 54.8 percent
count at the time of this writing.
