ENTIRE SUITE Separated all tests into navigation and test pages in preparation for use by additional CSS test suites. Added explicit charset declaration to pass latest validator. If you used the Test Suite before this revision, it is best to treat the new version as though everything changed, and re-run your tests accordingly.
20010423 (23 April 2001)
1.5 ID as selector Was not valid HTML. Removed the paragraph with ID="1". Made all the IDs unique.
19990126 (26 January 1999)
ENTIRE SUITE Major additions, clarifications, rearrangements, and other changes in preparation for making the Suite official. This includes the addition of the Prologue, the separation of Box Model tests into separate pages for block-level and inline elements, tests covering more of section 2, section 4, and section 7.1 of the specification, and a host of corrections and other alterations to the tests and text throughout the Test Suite. These changes are, unfortunately, too numerous to document here. If you used the Test Suite before this revision, it is best to treat the new version as though everything changed, and re-run your tests accordingly.

19980715 (15 July 1998)
5.2.7 font Changed the wording relating to line heights to be more accurate, correctly describing it as being related to the font size; also added a new test which uses a pixel value for the font size.

19980615 (15 June 1998)

1.3 Inheritance Fixed the declarations to include an omitted BODY rule, the lack of which was making some of the statements invalid; also changed color values of dark green to more obvious colors, based on user feedback that the specific dark green in use was too difficult to distinguish from black.

1.5 ID as Selector Removed a test for handling of duplicate IDs as being beyond the scope of CSS1.
