Platform-agnostic, sourced on every page, written for humans and agents. MIT licensed, open for pull requests. Live site: MCP server: What this is The web is a layer cake of standards: WHATWG defines HTML, W3C ratifies WCAG, the IETF publishes the RFCs behind security headers and /.well-known/ URIs, IANA registers the namespaces, search engines publish their own rules, browsers add quirks. Almost nobody carries the whole picture. This site collects the slices into one platform-agnostic specification — sources cited on every page. It is not a framework. It is not a tutorial. It is a spec, in the same way the HTML Living Standard is a spec: outcomes, requirements, references. What this is not - Not platform-specific. No \"use this Next.js plugin\" advice — the spec describes the outcome, you choose the implementation. - Not opinion. Where there is no settled standard, the spec says so. - Not a marketing site. No newsletter capture. No cookies. Aggregate Plausible analytics; that's it. Categories - Foundations — HTML, head, document basics. - SEO — search visibility. - Accessibility — WCAG-aligned rules. - Security — headers, transport, policies. - Well-Known URIs — agreed paths under /.well-known/ . - Agent Readiness — making a site legible to AI agents. - Performance — Core Web Vitals, caching, fonts. - Privacy — consent, signals, respecting choice. - Resili","default_branch":null,"files":null,"tree":[],"storefront":"/r/jdevalk","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/jdevalk/specification.website/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
