Use and content limits
Terms of use and content boundaries.
Use the reference as educational implementation guidance, verify important decisions against current primary sources, and test the product you actually ship.
01 · Permitted use
Use the site for interface research and implementation
You may browse pattern definitions, compare alternatives, use the browser-based diagnostic, and copy generated implementation briefs for your own design and development work. Source links remain subject to the terms of their respective publishers.
02 · No guarantee
The content is not a compliance certificate
The site provides reviewed educational guidance, not legal advice, a formal standard, an accessibility certification, or a guarantee that generated code is correct. Browser behavior, assistive technology, product context, and component-library implementations can change the required solution.
03 · User responsibility
Verify the result you ship
You are responsible for reviewing requirements, choosing dependencies, testing keyboard and focus behavior, checking responsive layouts, protecting user data, and meeting the laws and policies that apply to your product. Do not use a pattern label as a substitute for testing.
04 · Content and availability
Corrections may change the reference
Definitions, comparisons, links, and diagnostic rules may be corrected or removed as evidence changes. Report material errors to tangjei414@gmail.com. Continued availability, search ranking, and fitness for a particular workflow are not promised.
