HTML
Let an agent explain HTML and its role, relay syntax, elements, forms and standards from web standards sources, describe practices such as semantic and dynamic HTML, and distinguish HTML from CSS, JavaScript, XML and rendering engines.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain HTML and its role, relay syntax, elements, forms and standards from web standards sources, describe practices such as semantic and dynamic HTML, and distinguish HTML from CSS, JavaScript, XML and rendering engines.
The standard markup language for documents designed to be displayed in a web browser, defining the structure of web pages with elements for text, links, images, forms and form fields such as file selection inputs, maintained as a living standard by the WHATWG, with practices such as semantic HTML that uses meaningful elements, scholarly HTML for research articles and dynamic HTML that combines HTML with scripting and styling; HTML works with CSS and JavaScript as the foundation of the web.
What it is for: Structuring web documents.
It can be explain the language; relay elements and standards; describe practices; distinguish related technologies.

Physical character
first described: 1991 year - Tim Berners-Lee
HTML5 recommendation: 2014 year
living standard: WHATWG note - since 2019 sole standard
elements: over 100 count
How it is recognised
Markup language of web pages
Elements, web forms, form fields, file select inputs, semantic HTML, scholarly HTML, dynamic HTML
CSS styles; JavaScript scripts; XML is a general markup framework; browsers render

What the second pass must settle
- Should web form and semantic HTML be separate primary entries?
- How should web standards sources be linked?
- The registry entry has merged aliases naming form controls and practices; should they be split off?
