I thought I knew everything about CSS, but I'm learning a lot. In fact, I thought that in practice, I only used the properties that I used every time and that was enough, but after taking this lecture, I realized that there were many things I didn't know. I only knew about the Fontello site and didn't know how to use it, but I didn't know that I would learn how to use it in this lecture. I think it will be very helpful when working on my personal portfolio. If there are people who are wondering, "Is this really worth listening to? It's a free lecture, so what's there to learn?", I recommend that you complete it to the end. Thank you so much, Egoing :)
