Essential course for those who are seriously starting web design I recommend this course to those who are learning HTML, CSS, and JS and are seriously starting web design. Advantages Since the code is written in pure JS without using JS libraries, it seems to be good for laying the foundation. The difficult parts are briefly explained and then moved on, so if you think about it a little, you will understand. I felt that not a single second was wasted in the lecture video. Feedback I think it was a little fast for me. I think it would have been better if you had explained it with a little more specific examples. I had to endure a little inconvenience due to the small font size. (Dual monitors are recommended for those who are watching the lecture)
