This is a development version of the [% specName %] Test Suite.

It contains unreviewed tests and should not be used for testing CSS conformance. This build exists to aid in test development only. [% ELSE %]

It is woefully incomplete and may contain incorrect tests. [% END %] Please check the latest version of the [% specName %] specification before assuming a failure is due to an implementation bug and not a test suite bug.

In time we hope to correct all errors and extend this test suite to cover all of [% specName %]. Your help is welcome in this effort. The appropriate mailing list for submitting tests and bug reports is public-css-testsuite@w3.org. More information on the contribution process and test guidelines is available on the wiki page.

Tests are currently available in three formats:

XHTML 1.1

XHTML 1.1 tests sent as application/xhtml+xml

HTML 4.01

HTML 4.01 tests sent as text/html

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. Without the Ahem font installed, these tests are of no value.

Common Assumptions

Most of the test suite makes the following assumptions:

• The X/HTML div element is assigned display: block; and no other property declaration.
• The X/HTML span element is assigned display: inline; and no other property declaration.
• The X/HTML p element is assigned display: block;
• The X/HTML li element is assigned display: list-item;
• The X/HTML table elements table, tbody, tr, and td are assigned the display values table, table-row-group, table-row, and table-cell, respectively.
• The device can display the sixteen color values associated with the color keywords black, white, gray, silver, red, green, blue, purple, yellow, orange, teal, fuchsia, maroon, navy, aqua, and lime as distinct colors.
• The UA is set to print background colors and, if it supports graphics, background images.
• The UA implements reasonable page-breaking behavior; e.g., it is assumed that UAs will not break at every opportunity, but only near the end of a page unless a page break is forced.
• The UA implements reasonable line-breaking behavior; e.g., it is assumed that spaces between alphanumeric characters provide line breaking opportunities and that UAs will not break at every opportunity, but only near the end of a line unless a line break is forced.
