The whole globe? No. But the berne convention does have 179 signatory countries. It's not just "western".

"A copyright cannot cover ideas, procedures, or methods of operation. You can copyright your website’s design, but you can’t copyright the way you created the design." If you use the components to create a new design then there is no copyright.

The code they created, to implement that component, is an original creative work. Thus protected under copyright.

> If you use the components to create a new design then there is no copyright.

This is false. You can't copy a site's code and just change the design and poof, no copyright infringement.
