Websites using YUI Library
YUI is Yahoo's retired JavaScript and CSS library for building rich web interfaces.
About 6,365 websites in the PageSourceSearch index contain the code that reveals it; the 50 highest-ranked are listed below.
How is YUI Library detected?
Pages load YUI modules and the seed file from Yahoo's yui.yahooapis.com CDN. The discovery keyword is the exact bytes PageSourceSearch looks for in every stored page and script:
yui.yahooapis.com/ Search the index for it
A literal is matched byte for byte, case-sensitively. Combine it with another keyword, a domain, a kind or a date filter on the search page to narrow the list. About YUI Library

Questions about finding YUI Library
How does PageSourceSearch know a website uses YUI Library?
By the source itself: Pages load YUI modules and the seed file from Yahoo's yui.yahooapis.com CDN. PageSourceSearch stores the raw HTML and first-party JavaScript of each crawled site and matches the keyword byte for byte, so every listed site's stored source contains it.
Is this a complete list of websites using YUI Library?
No. The page lists the 50 highest-ranked sites in the index whose source holds the keyword, out of about 6,365 websites that do; the count is the index's estimate at the time the list was computed. Run the keyword as a search to page through all of them, or add a kind or date filter.
How do I find websites that use YUI Library together with another technology?
Search for both keywords at once: several terms separated by spaces must all be found on the same site, or with the Same page toggle in the same page. For example yui.yahooapis.com/ with wp-content/plugins/ lists the WordPress sites that use YUI Library.
