Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

A Programmable Markup Language for Typesetting [pdf]
HTML the markup language was clearly intended as an SGML vocabulary - TBL himself said as much [1] and HTML also reused element names from the SGML spec/handbook as example/folklore vocabulary such as for paragraphs and headings.
What browsers made out of it isn't the matter here, but even if it were, the "practical, real-world HTML out there" argument is mostly used to pull up the ladder by an ad company/browser cartel made worse day-in day-out through an atrocious and absurdly voluminous HTML spec (and by CSS, of course).
Even though Ian Hickson, of WHATWG, wanted to capture HTML as it was understood by browsers, he couldn't help but added additional elements of his own - such as for marking up ads as "aside" lol plus the alien sectioning elements concepts that gave rise to the flawed "outline algorithm" and misuse of heading elements (and earlier failure to understand SGML's RANK feature), a problem that was only fixed last year [2].
In practice, very few changes to the HTML syntax brought HTML outside SGML - for the most part, ad-hoc and basically unnecessary commenting rules for the script and styles element to keep legacy browsers from rendering JavaScript and CSS, resp., when those where introduced.
