Everything on this page — the accordion, the definition popovers, the notice — works with zero JavaScript.

Note: this form is a demonstration of the
<search> landmark — it is not wired to a
search backend, so submitting it goes nowhere useful. The markup is
the demonstration.

When results render, the matched phrase is highlighted with

Frequently asked questions
The three entries share name="faq", making them a mutually
exclusive accordion — opening one closes the others, courtesy of the browser:
Do I need an account to read the guides?
No. Every guide is public. An account only stores your reading position across devices.
Can I download guides for offline use?
Yes — every guide is a single self-contained HTML file. Save the page; there are no stylesheets or scripts to lose. See the note on .
How do I report an error in a guide?
Use the report link in the guide's footer, or email support@html-tags.com. Include the section heading so we can find the passage.
Self-contained page: a document whose images are data URIs and whose only script is JSON-LD metadata — nothing external to break. Press Esc or click outside to dismiss this popover; the browser handles both.
