Intended audience: users, HTML coders, script developers, CSS coders, Web project managers, and anyone who wants to know how language declarations work in current browsers.
These tests check whether user agents recognize language declarations for HTML documents, and apply the expected prioritisation in case of mismatches between multiple declarations.
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'.
Key:
pass | fail | partially successful |
Note that these test results are for released versions of the browsers tested. Versions that are still in development may provide better support for these features. The tests do not use any vendor prefixes. Tests that do show support for vendor prefixes are listed further down this page.
