CSS2.1

This test suite is provided to test browser's conformance to the CSS2.1 specification. Tests are currently available in three formats:

1. XHTML 1.1:  XHTML 1.1 tests sent as application/xhtml+xml

2. HTML 4.01 tests sent as text/html

3. XHTML 1.1 for Printers XHTML 1.1 tests with all images converted from PNG to JPEG and formatted with headers and footers to ease testing of embedded printer software. This is not a canonical format, and some tests may fail due to the format conversion that would otherwise pass in the above XHTML 1.1 format.

Note that many of the tests require the Ahem font to be installed. The tests that require this are marked with an 'a' at the end of the filename, after the test type classification. Without the Ahem font installed, these tests are of no value.
