What makes the book unique

Praise from readers

John Allsopp

Web Directions, @johnallsopp

CSS is sadly an increasingly undervalued tool for front end developers, in no small part because developers find debugging CSS challenging. Yet, until now there's been little in depth published on debugging CSS. Ahmad Shadeed's book is long overdue, and I can't recommend it highly enough for any front end developer.

Geoffrey Crofte

Lead Design System, @geoffreycrofte

Ahmad gathers in this practical book a bunch of CSS bugs encountered on a daily basis by all levels of developers, and how to solve all of them. A book that would have saved me hours of research in my early days, and well, still today! Well done!

Zoran Jambor

CSS Weekly, @ZoranJambor

Debugging CSS is a must-read for anyone who wants to improve their CSS knowledge, regardless of their experience and expertise. In this book, Ahmad Shadeed scrutinizes and dissects all aspects of debugging CSS, which will help you spot and fix problems in your CSS more efficiently and much faster.

Ahmad is one of my favourite tech writers because they explain concepts in such an approachable, inclusive manner. This book is a no different. I couldn't recommend it more if I tried!

I've had this book for just a few hours and it has already helped me debug a layout shift issue!

Just purchased your book. Searched for an issue I've been struggling for a long time. Used the tip to find the issue. What a treat!
