It was great that even a complete beginner like me, who lacked the basics, could understand the concepts clearly and move on! And the real advantage was being able to create a portfolio page at the end!!! _Nam Yoon-jung

This book covers everything from the basics of HTML, CSS, and JavaScript to how to use them, and carefully selects the content that is essential for practical use.
Since it was my first time coding and I didn't know much about the content, the explanations were easy to understand, so I was able to study with enjoyment until the end.
If you've just started studying but don't know what to do on your own, read this book.
This will be a great opportunity to set a direction for your studies in web development and gain practical experience while implementing it yourself.
_Kim Dong-won

I liked this book because it contained a lot of information in one volume.
It was a very useful time reading the book because it not only covered things that I was curious about while studying, but also included techniques used in practice.
_Park Ga-dan

It is a friendly textbook that will help you gain a lot.
I really enjoyed it because I could study smoothly without having to look for other materials.
I highly recommend reading this book to anyone who has ever visited the portfolio site we'll be building in the final chapter and thought, "I want to create a website like this."
The example site provided is also very useful, allowing you to learn the basics of web development easily and conveniently.
_Kim Seon-hye

It was a book that I looked up out of curiosity rather than feeling like I was studying it.
Although it was a book for beginners, it was full of useful tips for practitioners as well, and it was so good that I wish it had more explanations of basic concepts.
_Hong Jeong-ah
I thought that someone new to coding would be able to build a solid foundation without getting lost with just this one book.
It was even more useful because it contained details that I hadn't seen in the textbook before.
This book is incredibly rich in examples and covers everything a practitioner needs, making it a great help to both complete beginners and those who have already mastered the basics.
_Ryu Seong-ju

This book is well organized with basic concepts that are easy to miss, so even practitioners can keep it handy.
It's full of practical tips that apply what you've learned, from the basics up to expert knowledge, so it's useful at any level.
It is also a book that is suitable for self-study as you can feel a sense of accomplishment by calmly following the examples and projects and practicing.
_Kim Ji-won

The meaning and usage of HTML, CSS, and the JavaScript programming process are explained in great detail so that even beginners can easily understand and follow along.
When you encounter a slightly difficult part, we provide tips and advice along the way to help you successfully overcome the long and arduous process of learning web development.
I felt that it was by no means shallow knowledge, and I am confident that if I can fully master this book, it will be of great help in my next level of study or in studying various JavaScript frameworks.
