Just to be clear, the vague-remembered article that I read /didn't/ warn
against mixing different units (eg. mixing pixels and ems or ems and
percentages); it was specifically warning about mixing units /of any
sort/ with keywords.
(Which isn't to say, of course, that mixing different units doesn't
bring its own set of dangers, but that's a different issue and unrelated
to rules being ignored).
