Debugging CSS book testimonials

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.

Browser DevTools help us a ton these days in debugging CSS, but there isn’t exactly a step-by-step guide about it that I know of. This book leans into that, showing off how to debug really practical and understandable CSS issues with the help of DevTools when appropriate.
