Sass grammar is grammar, but I was curious about how to organize and use folders when working on a project, and I learned a lot about that while practicing the Lorem project! Originally, I used brackets, so I had a high barrier to vs code, but it was good that I was taught vs code step by step, from extensions to environment settings, from the beginning. I'm going to work with vs code now! In addition, it was really helpful that the confusing em, rem concepts of CSS and animations were well organized.
