This report was prepared to document the current implementation status of the CSS Fonts Module Level 3 (CSS3 Fonts) specification as of 11 December 2013 and is based on current test results available in the W3C Conformance Test Harness.
Twenty three user agents, built from seven rendering implementations, were tested across eight operating systems.
The 20 July 2013 revision of the CSS3 Fonts test suite was used. The test suite consists of 367 tests.
These tests are available in several host language variants:
Some tests only apply to certain language variants; the results for each tested implementation are reported for each tested language variant. Also, not all tests are applicable to each implementation; for example, a browser which implements HTML but not XHTML is not tested for XHTML.
In summary, the results show that 366 of 367 tests were passed by at least two of the tested implementations.
Results were gathered from implementation reports submitted by user agent vendors as well as the general public via the W3C Conformance Test Harness.
