I understand and agree with the sentiment expressed here regarding the outer layout of components in a page (though I'd actually recommend using `gap` with a flex or grid layout).

But margins can be incredibly helpful when implementing internals of complex components, and when laying out components next to each other that are not equal peers (like labels with form fields).

Negative margins can also be very helpful in some circumstances, like when a border shouldn't contribute to the space taken by a component, or when components should overlap without resorting to absolute or relative positioning.
