Amazing book
Format: Paperback
One of the standout features of this book is its stunning design. Each page is meticulously crafted with vibrant colors, clear diagrams, and engaging layouts, making complex concepts easy to understand and visually appealing.
But beyond its aesthetics, the content itself is top-notch. Duckett breaks down HTML and CSS in a way that’s approachable and easy to digest. Whether you’re learning the basics of structuring web pages with HTML or delving into the intricacies of styling with CSS, the book provides clear explanations and practical examples every step of the way.

I was lost almost immediately
Format: Paperback
I am sure this is a wonderful introduction for someone who already knows a bit about coding. But for the absolute beginner, it leaves much to be desired. It assumes more experience than most people starting from scratch would normally have. This is a common problem with texts by professionals who do not get input from amateurs.

HTML and CSS Guide: Readability
Format: Paperback
I am using this book as a supplement to my certificate program. Having an additional reference or alternative perspective on resolving various coding situations is helpful. The authors' readability and simple approach are beneficial. Simple is always better.
