## What it is
A free visual reference guide to all HTML5 elements and attributes, published at htmlreference.io. The site is built as a Jekyll static site with content licensed CC BY-NC-SA and source code MIT.

## Use cases
- look up what an HTML element does
- find all available HTML attributes for an element
- learn HTML by example
- check whether an element is inline, block, self-closing, or experimental
- browse a complete list of HTML5 elements

## When to choose
- you need a quick, visual, example-driven HTML reference
- you are learning HTML and want free documentation of every element and attribute

## When to avoid
- you need up-to-date documentation on brand-new HTML features
- you need a CSS reference (use cssreference.io instead)
- you need an interactive validator or linter rather than a guide

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, markdown
- domain: web-development, frontend, documentation, education
- platform: cross-platform
- tags: html5, reference-guide, jekyll, static-site, html-elements, html-attributes, web-server
