Hmm, this is my personal opinion. I studied HTML and CSS on my own, and I bought a course for Java Script for the first time. I personally think that the level of understanding was really good. Since this was my first time with Java Script, I learned more about the basics of CSS transform, transition, and rotate, and I learned CSS 3D for the first time, but I personally really liked it. There are many practical courses, and it seems that even beginners can understand it, so I can see that they put a lot of thought into it. I also thought a lot about creating my own special, completely sexy interactive web! I chose this course for the first time, and I think I made a really good choice as my first step in Java Script^^ Of course, the last step forward! It was a bit difficult from the 20th round of 3D scrolling, but lol... The process of repeating and struggling was also fun (I did it twice from the 20th round.) I'm going to go watch the 3D leaflet course now! Fighting to all the developers and designers~! This is so much fun! Fighting!!
