You're talking about CSS. I'm talking about classes.

> `class="m-0 md:m-4"` is more legible because it describes exactly what is happening

If by "what is happening" you mean "how it's styled", but that's extremely presumptuous. You might as well argue that there's no difference between Flash and an equivalently styled web page since if you took a screenshot of each they'd be visually identical—as if the whole thing begins and ends with getting the "rectangle full of little lights" to change in a particular way <https://xkcd.com/722/>. It's very narrowminded.

I'm not saying you have to be full on schema.org-conformant, but include something that actually makes sense instead of being as useless as the spew that CSS compilers put out.
