HTML+CSS Internationalization Tests
Selectors

This page groups together pages being developed by the Internationalization Core Working Group to assess internationalization support of user agents. These tests are still under development and should not be taken as final.

Note that Internationalization WG tests do not only test conformance with W3C standards. In some cases the tests also allow for exploration of the behavior of user agents in ways not described by the standards.
