Sigh. Yes, yes, I
know it's the target audience, but the pitch is always, always the same:
Without coding, create a professional-looking website or online store
Coming soon:
Without learning to read music, perform a piano concerto in a professional looking concert hall Without any still-life drawing experience (or any artistic experience at all) have your artwork displayed in a professionally presented public gallery Without having developed even a basic level of literacy in French, publish a short story for Parisian readers in a professionally presented journal I don't think it helps that HTML and CSS are casually referred to as "coding".
(It's arguable, in some contexts, that "coding" is not always an entirely inappropriate category for these technologies, but in the case of HTML5, a simple declarative syntax with two dozen element names and attributes is not approaching the impenetrable depths of C++ or Swift, so calling everything "coding" can lack nuance.)
You can go a really, really long way with just markup and styling.
The first of these (and the basics of the second) can be learned in a weekend if you're flying along and in a month if you're taking things really, really methodically.
And no, markup and styling are not for everyone.
But what about all those many, many people who they are for, but who don't know enough to know that?
What if all you were ever told was that if you're planning to join the monastic orders it's not worth learning to read or write? You'd probably still be illiterate, right?
Markdown and its variants were a huge gift to the world. The vast majority of even well-educated people have never heard of Markdown.
Markup: It's. Just. Punctuation.
