While waiting for a job after creating a portfolio and uploading a resume, I am listening to this to gain a more solid foundation when I go to work~ As expected, I am very good at listening~ The parts that I was curious about in the past, "Why is that?" parts are explained well~ And There are also things that make CSS code more concise~ I haven't heard everything yet, but this is a valuable lecture that will help me not get lost when I go to work~ Thank you^^
