This report was prepared to document the current implementation status of the CSS Color Module Level 3 (CSS Color 3) specification as of 24 October 2016 and is based on current test results available in the W3C Conformance Test Harness.
Two user agents, built from two rendering implementations, were tested across two operating systems.
The 24 October 2016 revision of the CSS Color 3 test suite was used. The test suite consists of 70 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 1 of 70 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.
