This report was prepared to document the current implementation status of the CSS Style Attributes Level 1 (CSS Style Attributes 1) specification as of 8 October 2015 and is based on current test results available in the W3C Conformance Test Harness.
Seven user agents, built from five rendering implementations, were tested across four operating systems.
The 8 October 2015 revision of the CSS Style Attributes 1 test suite was used. The test suite consists of 16 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 14 of 16 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.
