Small partners interested in web front end technology can be added to our learning circle, because I am not 211985, just an ordinary undergraduate student, English is not particularly good, and math is not particularly good. So I chose the front end. In my sixth year of work, I am glad that I have chosen this road. 767-273-102 autumn skirt. I worked in a goose factory, and I fooled with the entrepreneurs. I want to share my technology with you. If you are still confused, I hope to help you with some of my meagre efforts. It's a group of people with dreams. We may be in different cities, but we will go together. Front-end, front-end, front-end

Design sketch

The main thing is to set the depth of field perspective, and then rotate and translate each surface.
