Flexbox Explained is a fun and enjoyable introduction to Flexbox. Over the last fifteen years, Jorge and Steve have worked as web designers. It's been a fascinating time. For many years, the most popular way to design websites was with frameworks such as Bootstrap and Foundation. These frameworks were necessary because they added many features that we needed. The core features of CSS weren't enough for modern web development. However, in recent years, the developers behind CSS worked to create "modules" including CSS Grid and Flexbox. These provide many of the features we need, but without requiring us to install anything.

You can use Flexbox simply by writing code in a file and opening your browser. That's what we do throughout this book! You'll learn Flexbox by completing exercises that explain all the key properties of Flexbox.
