How to bring this svg animation to the site?

Question

css

Here is the site (drugoy-kuzovnoy.ru/), and instead of the blue block, I want to insert this animation , but I'm not sure of my knowledge, if the css code I know that it should be added to style.css. Then with javascript, I'm not sure whether it should be entered in customizer.js . But I can't find the html code. Of course, the question is rather stupid, and I myself would not answer it, but thanks for at least reading it
