Intended audience: users, HTML coders, script developers, CSS coders, Web project managers, and anyone who wants to know whether browsers support the CSS Ruby spec.
Updated
These tests check whether user agents correctly apply the property hyphens per the CSS-text-3 spec. The hyphens property with the auto value requires access to language-specific hyphenation resources. These tests don't examine behavior on a language-by-language basis, but assume the availability of an English hyphenation resource to test general principles. For more information about language support, see the table in the MDN documentation.
To see the test, click on the link in the left-most column. To see detailed results for a single test, click on a row and look just above the table. The detailed results show the date(s) the test result was recorded, and the version of the browser tested.
Any dependencies are shown in notes above the table, and notes below the table will usually provide any additional useful information, including an explanation of why a result was marked as 'partially successful'.
Results for prefixed keywords use -moz, -webkit and -ms. They are, however, for released versions of the browsers tested.
Key:
