HTTP header and meta element
Assertion holds if you see green below.
This test is only valid if the user agent recognises the HTTP and meta declarations, and :lang works.
| Ignore this test. (:lang not supported) |
Assertion: [Exploratory test] If there is a conflict between the language declarations in the HTTP header and the Content-Language meta element, the UA will recognize the language declared in the meta element.
Notes:
Red means the HTTP declaration had precedence.
