Voice? Volume? I was embarrassed because it was so low. When I turned up the computer volume and listened, the machine sound was also too loud in the middle.. ㅜㅜ He spoke so slowly that I usually listened at 1.75x or 2x speed. It was a bit boring when I set it up in the beginning. But as it went on, the content became a work of art. The lecture's technical aspects are a bit lacking, but it contains content that can be covered 120%. I'm a 3rd year coder and when I tried to develop a full stack, I realized that I didn't have enough CSS knowledge, but when I studied CSS, I only studied the basics and it was a repetition, but through this class, I was able to take an intermediate class, and it was a lecture that I didn't want to miss even a minute because it showed various applications. I finished it in 3 days, but I'm going to listen to it again while taking notes calmly. The settings that I found a bit boring at first turned out to be useful! I look forward to more great lectures in the future!
