Find a better CSS methodology for allowing component consumers to customize component's layouts

[marinaaisa]

Find a methodology that allow us to balance between scoped styles and being able to modify child elements from their parents in CSS.

This issue is created because we should be able to find a better solution for .copy-container:not(:only-child) (check the context and problem) and also avoid this kind of approach that I suggested since it's following an anti-pattern called coupling. Thanks for the feedback, @delapuente

Don't hesitate to contact me if this issue is not properly explained.

Let's try BEM without removing scoped when possible and being flexible with the inner hierarchies, trying not to over-componentize.
