I am using some code from Material Design Lite's example portfolio. The html and css is under a Creative Commons Attribution International 4.0 License, but the repository states:
As an exception to this license, all html or css that is generated by the software at the direction of the user is copyright the user. The user has full ownership and control over such content, including whether and how they wish to license it.
I'm not really sure what the above blockquote means.
