HTML.md

This article presents a draft for an 'HTML.md' specification file, following a trend of specialized documentation files. It outlines three core instructions for writing HTML: use semantically appropriate elements, use minimal HTML, and validate all output against a W3C validator. The author clarifies this is not a joke but a serious call to improve HTML quality, addressing common issues like 'divitis' and invalid code. While opinionated, the guidance focuses on foundational practices rather than covering all aspects like accessibility or performance. The article encourages developers to pay more attention to HTML quality, though adopting 'HTML.md' as a convention is left to individual choice.
