It's not enough 5 stars. I think it's the Ivy League lecture of CSS. I really respect the instructor. This is a lecture that even the creator of this language would praise. I'm surprised that this many people have taken the lecture. It must be 500 million people. I regret the time I spent worrying whether to pay or not.. I've taken so many lectures, so I was worried that this one would be ...... not so good. This lecture shows the spirit of open code very well. I've read many HTML CSS books, and I've been to many famous academies. But there's no one who teaches code this kindly. In the case of developers who know code well, they don't know much about design, and they just memorize it, and The lectures given by designers... had poor content. They only put up a sign, are expensive, but are rude, and only emphasize their name value... academy books or marketing mix.... I'm really sick of it. If there's a god of CSS, it's Professor Lee Dong-ho ~ :) I regret the time I wasted going to offline lectures and the time I was annoyed by the book and said, "What is this?" I can say that this lecture is a great lecture now If I hadn't wasted that time, I wouldn't have known about this lecture, it's a pearl in the dirt. Professor Lee is really a god of CSS I want to meet you and buy you a meal! I always thought I was a CSS novice, but I think I can master it with just this one lecture. Even before I finished the lecture, I'm leaving a review first because I was impressed by the abundant examples and logical and kind explanations. May you be blessed, instructor!
