Copyright for the design in the layout designer's portfolio?

Question

Design

There is a portfolio of a layout designer / front-end developer, where the completed works are posted. Design of individual sites, UI kits, etc. was developed not by the author of the portfolio, but by other people. Is it necessary to include a footnote somewhere explaining that the design of the works belongs to their authors, and the works cited are only an example of the implementation in the code? And are there any other pitfalls in this situation?

Answer 1

What is copyright? Who to pay? With this approach, all programmers would have to unfasten a considerable percentage of Stack Overflow, Toaster, etc. One either knows or one does not. Either tell why the code works or it doesn't.
A programmer's job is 50% ctrl + c, ctrl + v.
Based on trust and conscience. That's all.
ps copyright may be on the product, not the code.
