This book teaches CSS Flexbox beyond properties and syntax. It explains how layout systems actually work in real-world applications, where space, constraints, and content interact in complex ways.

In the first part, you will learn how Flexbox behaves, how its properties interact, and how layouts are constructed and controlled. In the second part, the focus shifts to mental models: understanding layout as a system of constraints, trade-offs, and behavior under change.

Instead of memorizing rules or relying on trial-and-error, this book helps you build intuition. You will learn how to reason about responsive layouts, predict behavior before writing code, and design systems that remain stable across devices and content variations.
