This is an interesting perspective, and one that could only exist in the past few decades.
For millennia, of course, the written word would appear in the particular style of an individual scribe, and might take on an entirely different look when copied by another. Gutenberg’s movable type introduced the concept of a text appearing exactly the same across multiple copies, something that has persisted for centuries through lead type, phototypesetting, and into PDFs. Only with the advent of information technology in the 20th century did the idea arise of text appearing in formats other than those chosen by its publisher, advanced by technologies such as TeX and HTML.
In the latter’s case, however, the original idea of a platonically structured document to be interpreted per the user’s preferences has long since been superseded by a return to the concept of the publisher defining the presentation. Client CSS never caught on, while server CSS took over.
