It's a cool idea that the Tailwind marketing site shows tailwind classes inline to express how it works...
But, I wish they were honest about what classes they actually used. The inspector's right there lol
Here's a screenshot of the page next to a screenshot of the page showing the classes they actually apply to the heading and subtitle

A screenshot of the Tailwind site. The heading and subhead show a _ton_ of Tailwind classes above them describing the styles applied to them
